I had completely cleaned my computer of virus and re-installed Sims and the game was working (with several annoying errors, but at least running). But, I recently installed a couple of hairs (low-polycount, by Anubis) and the game has begun crashing once again.
I deleted my DCBackup folder contents (other than ccmerged) and saw that in my DCCache folder, there was a file called missingdeps.idx
Any clue if this may be the problem?
