Ok i have the Adobe Flash CS5 pro trial version and i found a serial number that when i entered it it said that the serial number is valid for the product Adobe Flash CS5 Pro, (Which is the one that i have). Then i clicked continue. After that i finished a project, and i exited out of it. Then later i opened the program again and it said that the serial number was invalid even though it clearly said that it was for Adobe Flash CS5 pro that same program that i have. I have internet connection and all, and i just need help to know why it did that and if any spare serial number for Adobe Flash CS5 are available and operational.
