Here is a quote:
“Renewal
The price is valid for a full 12 months. After that, we’ll renew your contract automatically unless you cancel. The price is subject to change, but we will always notify you beforehand.”

As a result of your experience I had this interaction with Adobe Customer Service:

Sharan: As I understand, you wish to stop the auto-renewal feature of the Adobe Creative Cloud subscription. Is that correct?
Steven: Correct. I do not want the subscription to “auto renew” at some unspecified price. A friend was recently burned by that.
Sharan: Thank you for the confirmation. I’ll be glad to check and help you with that.
Sharan: Your account is set to auto-renew so that you don’t experience any interruption in access to your product or services.
Sharan: I am sorry to inform, we do not have the option to disable the auto-renew feature.
Steven: Ok, then can I inform you now that I wish to cancel my membership effective May 14, 2014?
Sharan: Please allow me a moment to check with your subscription information.
Sharan: I see that the annual Creative Cloud membership was purchased on May 16, 2013 and the one year term ends on May 15, 2014.
Steven: Yes, and I do not wish it to renew after that. Since I cannot turn off auto renew, I’d like to formerly end my subscription on May 14, 2014. That way I won’t have to worry about failing to cancel it, or getting “renewed” at an unaffordable price.
Sharan: If you do not wish to continue the subscription, you need to contact us back to cancel the subscription from being charged further.
Steven: But, my agreement is for 1 year, not beyond that. Please show me where in my contract I agreed to be charged for any subsequent year.
Sharan: Please click here for the information on membership of Creative Cloud
Steven: I’ve read that page many times over. Nothing indicates I cannot stop auto renewal or that I am obligated to pay for subsequent years without prior authorization.
Sharan: Please allow me a moment.
Sharan: Click here to review the Creative Cloud Subscription Terms
Steven: When will I be notified? My friend got NO notification! But thanks for pointing that out… you violated your contract with him.
Sharan: Before 2-3 days before renewal date, you will receive a notification regarding the auto renewal
Steven: 2-3 DAYS? That’s all!? What if I’m out of town? What if my internet is broken? 2-3 MONTHS would be acceptable.
Steven: I held on long enough to get the promised CC content. At this point if you are unable to allow me to cancel auto renewal, I would like to cancel my subscription and get a full refund. At $20 the cloud is quite reasonable. At $50 it is not. And I don’t even know what you’ll be charging then!
Sharan: I checked and see that you will receive the email notification before the 12 month renewal.
Sharan: However, we cannot assure when exactly you will receive the email confirmation.

Finally, I’m curious, Bob what Adobe would do if you cancelled your subscription and rejoined. If you have any CS3 or later product the discount is still available. This reminds me that I must turn off the “auto renew” feature. Unfortunately, it looks like Adobe hasn’t provided a way to do that.

I have downloaded several programs, including Photoshop CC and found the download and install to be very fast (I have SSD storage on my MacBook Pro laptop). The new features in PS CC (I was using PS6) are not extensive and several of my plug-ins didn’t migrate (NIK especially); however, I was able to copy them from my PS6 plug-in directory to the PS CC directory and everything seems to work fine. One interesting note is that the Advanced Stacker Plus did migrate and appears to be working properly.

Thanks Steve!!

Good news the ACR 8.1 update (no longer a Beta) can be installed by Adobe Application Manager now (June 17, 2013) without blowing up as I noted earlier.

Bad News: Today is when CC is supposed to be released, but I notice the text has been changed from “Available June 17th” to “Available in June”) . The individual product pages (e.g. Photoshop) make no mention of when CC will be released, and the Adobe Application Manager still shows only Photoshop CS6 in the catalog.

I now see that they’ve said the release will be at 9 PM PDT… We’ll see!

Having a bit of trouble using AS+ with CS6. After creating the black background, I begin to batch stack using ‘Comets’. After the first image appears, I receive a window stating ‘The command ‘Set’ is not currently available’. After clicking on continue, I receive a window stating ‘The command ‘Merge Visible’ is not currently available. After continuing again, the action does it’s thing until the next image appears where I get the same warnings.
I ‘continued’ through the entire file of images and have a layer stack of numerous layers all titled ‘New Background’ with a black layer on top titled ‘Stack Result’ with no results. Has this happened to anyone else? Thanks for your time and efforts here!

I’m using 8 bit TIF images and Windows 7 if that helps.
