The Serial Number you entered is invalid
Our copy of Adobe Photoshop CS6 spontaneously said it was in trial mode, then asked us to enter our serial number. When we entered the serial number we used for the original installation, the installer came back with "the serial number you entered is invalid. Please try again. If the problem persists, contact Customer support".
We contacted customer support via "live chat". It was very disappointing. We provided the agent with the background of the problem, gave them our serial number, and gave them a screenshot of the error we were getting. They then said that "this issue isn't supported by live chat" and redirected us to this forum. Not helpful at all.
So, now we need your help. What do we do? Who do we contact? Our production is down until this issue is resolved, so we need help ASAP.
I have been very disappointed with Adobe's support on this issue thus far, especially since so many other people seem to be having similar issues and are not getting answers in this forum.
