I have a user running a Dell D420 w/ XP SP3 and CUPC 7.0.2. During the login authentication process for CUPC, the application crashes. This user can login to CUPC with his un/pw on another computer. When I attempt it with my un/pw on his computer it crashes as well. I've also tried a separate profile. When putting in an incorrect un/pw, it does come back with a un/pw error and doesn't crash. It seems it happens when it actually authenticates. I've disabled the AV, removed most of Wave Systems' software except for Document Manager Lite and Personal Information Manager and reinstalled CUPC (twice). I'm out of any logical suggestions at this point. Any ideas?
