Downloaded Photoshop Elements 11. Entered (double-checked and even re-entered to no avail) serial number and got this message. Did the "chat" with Adobe and they couldn't help, told me to call Adobe tech Monday.
I DID buy the program from Costco and it's a "special edition" but don't know why that should matter. The serial number is in the same place as the programs you buy anywhere else. Maybe it's not matching on the Adobe site for some reason? Any help much appreciated.
