Have you tried re-downloading the Sims 2 Hack Conflict Detection Utility to restore the
SWsupport.dll file, and making sure you have at least
Microsoft .NET Framework 2.0 for it to run correctly?
Also, have you tried pulling out the custom objects you've downloaded since the last time you were able to play the game? You may have an incompatible/corrupt object mesh or hack that's causing problems. :angel:
