Kimmy9999 which operating system are you using? I checked your activation history for your copy of Photoshop CS6 Extended and it does appear that your computer is affected by the issue you posted in your original message. In effect your computer is identifying itself as two separate computers to our activation technology which is why you are prompted to enter your serial number again and activate.
The most recent update I have regarding this issue is that we are currently working with Microsoft to investigate the root cause of this behavior.
