I'm having real woes with my serial number for Adobe Flash CS4 Professional.
I trialed the software with the free 30-day trial. It ran out today, so I clicked the link to 'Buy a serial number for Adobe Flash CS4 online'
All good, bought the license and Adober have sent me my new serial number.
BUT IT DOES NOT WORK?! It just says 'The serial number you entered is not valid'
I've gone through all the customer services help and quadruple checked everything. I need this working in the next hour for a deadline - please please help!
I've just had this problem, but I fixed it by uninstalling then reinstalling Flash. It then accepted my serial number with no difficulty.
