I deactivated one of my Premiere Elements 11 serial numbers so I could use it on another computer and the serial number no longer works. Now I can't even reactivate my previous comuter I just Deactivated!!! HELP!!
Since version 11, activation is also related to your Adobe logon. So make sure you're logged out of your installation(s) of the program.
But if that doesn't fix it, you'll have to contact Adobe custom care via chat and have them reactivate for you.
