We are unable to validate this serial number for CS6 Design Standart. What's wrong with my key or why won't it validate?

I bought the CS6 Design Standard student and teacher edition over amazon. I activated the product on my adobe account and got a serial number. But when I install the package and enter the serial number I a message saying "We are unable to validate this serial number for Creative Suit 6 Design Standard. Please contact Customer Support."
Does anyone know what is up with this? I am sure that the problem isn't anything along the lines of making mistakes when typing in the serial (tried it multiple times, used copy paste to reduce chance of error). It's also not any problem with me lacking an internet connection adobe to validate the serial.

Serial number questions can't be handled on the forums. You'll need to talk to Customer Support either by phone or web chat.

When I try to install CS6 Design and Web Premium from a disk I get this message "We are unable to validate this serial number..." What is the reason for this?

I purchased a disk copy of CS6 Design and Web Premium from a reputable seller last week and when I try to install it with the serial number I got it says "We are unable to validate this serial number for CS6 Design and Web Premium. Please contact Customer Support." What is the reason for this?
Is the serial number invalid?

Hi Ned,
Thanks for the suggestion. I eventually got in touch with Adobe Technical Support and it turned out that my Adobe Application Manager was not the latest version. They downloaded the latest version and installed it and that seemed to solve the problem. I was able to install my CS6 Creative Suite and validate the serial number. All seems to be going well at the moment.

After installation it says unable to validate this serial number for Acrobat Pro XI. Why? What do I do?

I received my serial number online and went through the installation process. After it was successfully installed I wend to open Adobe Acrobat Pro XI and followed the prompt to enter my serial number and then received this error message "We are unable to validate this serial number for Adobe Acrobat Pro XI. Please Contact Customer Support."
I've read several FAQ and troubleshooting discussions but none have touched specifically on this.
I would have called customer support but did not see a number to call.
Does anyone know what exactly is wrong or what I can do to resolve the issue?

If you want to buy the product Lightroom 6.0 from the Adobe Website, then please visit here-
http://www.adobe.com/products/catalog/software._sl_id-contentfilter_sl_catalog_sl_software _sl_mostpopular.html
And scroll down to the bottom and spot the Lightroom 6.0 to buy the standalone application.
You can buy the application as an upgrade or full product (second red box in the screen shot shows the previous version of the software you own and needed to be selected if you are buying the upgrade Lightroom 6.0 ) in case you have the previous version ( Lightroom 1.0, 2.0, 3.0, 4.0, 5.0 ) serial number registered or noted somewhere.
Here is the screenshot which might help you in buying the product correctly,
You can visualize the first red box where you need to select on the drop down to make the purchase as an upgrade product or the full version of the application.
If you have the qualifying product ( Lightroom 1.0, 2.0, 3.0, 4.0, 5.0 ), then it would cost you just $79 else $149 in case of full installer.
Try, it might help you get over the plight of buying the product.
Thank you so much.

I've uploaded Acrobat XI Pro and it freezes when I'm using it. I uninstalled and re-installed. When I login, it says that it is unable to validate the account and has an option to use the trial. How do I fix this?

Unable to Validate Muse Subscription - fixes not working

I have the same problem that others have had with the error message "Unable to validate your Adobe Muse subscription. We haven't been able to validate your Adobe Muse subscription for some time. If you don't connect to the internet in the next few days, Adobe Muse will no longer be able to launch."
I subscribed to Muse in Dec. 2012 & have been billed monthly successfully for the last couple months, however I recently changed the card number to be charged - could that be the issue?
I am not signed up for Creative Cloud, which one of the discussion solutions seemed to mention, so might that be part of the problem? But if so, why now after a couple months with no issues?
Where the error message mentions connecting to the internet, I'm not sure what that means or how to do that - does that have something to do with Cloud?
I'm building a new site & we're not yet ready to publish, so we aren't ready for hosting, but I'm hoping that is not part of the issue?
I've tried some of the solutions posted in discussions (e.g., deleting certain folders & files), but before I uninstall/reinstall Muse, I'm hoping someone can help. I'm down to 1 day on the clock, so I'm hoping not to be shut out of Muse.
Any help would be greatly appreciated.

I had the same problem this week. Amy via @AdobeMuse on Twitter sent me this solution:
http://helpx.adobe.com/muse/kb/error-unable-validate-your-muse.html
In following the steps provided in this URL, I discovered that somehow the Firewall in Norton Security Suite had been set to block Muse, although all the other Adobe CC products were set to "Allow" in the Norton firewall.
By changing "Block" to "Allow," Muse now opens fine, but fair warning: I lost all the Muse sites I had been working on by following the other steps in this URL.
I suggest that the first step in the instructions in this URL should be changed to: check your firewall first to see if Muse has been blocked. If I had done that first, it appears that I would not have lost 10 months of work.

I am unable to get Lightroom Mobile to work on my home network. The Ipad says "There are no collections to sync, enable lightroom mobile on your computer", but it is enabled. I got it to work one time on another network but not at home where I use Lightroom.

Hi,
could you please give us some info on what kind of network you have?
Can other application communicate with the web?
Thanks,

Did you upgrade from 4.1?

Installation: hello, I am trying to install my adobe elements twelve. I have a serial number, which contains no letters (only numbers), from the box. I use a mac. When I try to install it, it says it's unable to validate my serial number. I have already checked the spelling. What should I do?

Does it begin with 1057? If not, it's a redemption code. In which case, see here:
Redemption Code Help
If it is a serial number, go to system preferences>security & privacy>firewall>firewall options and be sure that PSE is allowed to call out.
