I just bought an upgrade for my ae cs3 to cs 5.5. When I enter the serial that adobe sent me into the trial version it says that the serial is incorect. I've double checked and cs3 can upgrade to cs5.5 and I've quadruple cheked that I've entered the numbers incorrect. Anyone ever have the probelm and know how to solve it?
You simply need the proper installer. Upgrade serials do not necessarily work with the trial, since it cannot verify the serial of the previous qualifying product. Download the proper installer from your account or wait for the discs to arrive. I'm not certain since these things change too often, but also the current trial installer may in fact cover this scenario already, but you definitely need to run it again and install CS5.5 a second time. nothing's lost by at least trying...
Thanks Mylenium! I'll give it a shot!
