Katie:
I updated to 12.5.1 using the 01/19/07 installer this afternoon. I was able to launch the program once without problem. I was adding some custom plant symbols to the file PLANT SYMBOLS.MCD when the program became unresponsive. I had to force quit. When I attempted to re-launch, VW is requesting a valid serial number. I added my serial number, and it is not be recognized. I have even tried some of my previous SNs for release and beta with no success.
I have run Disk Utility for disk permissions and repaired a few problems. Still no success with the Serial Number.
Where do I go from here???
