I'm running the sims 3 on a 64-bit machine without problems. The game isn't installed on C:\ though, but on a different disk.

I have a problem with CAW's latest version. When I try to save a world in the edit in game mode, I get this error message:



I get a similar message even if I try to save a world without lots.
Any idea what the problem could be?

Edit: problem solved!
