Ok I broke down and bought Photoshop CS5 extended. So I enter the serial number and begin to use the program. No problems. A day later when I open it up it says to enter my Adobe ID - "otherwise" Adobe reserves the right to reduce any complementary subscription period. Whatever that means. I can still use the program but periodically the request for my Adobe ID pops up. I don't understand why I have to enter an Adobe ID just to use PS CS5. Can anyone here shed any light on this? I figured after spending 700 big ones for a legal serial number that would be enough for them.
