Game/BodyShop won't start

[weetzie]

OK, so this morning I was playing around in BodyShop, and then finished up and quit the program. I went away for a bit, and when I came back about an hour later, I discovered that I'm unable to open BodyShop or The Sims 2. Either program is listed in Processes in Task Manager, and then about 10 seconds later it completely disappears and nothing happens.
 
I haven't downloaded anything since, and I've tried removing my Downloads folder anyways. All I did in BodyShop earlier was delete one Sim and create another.
 
This has been driving me nuts. I've run my anti-virus software, as well as Ad-Aware and Seek and Destroy, and even Perfect Disk. Nothing has helped. I don't have any other non-system processes running aside from explorer and windows updater (which automatically runs, even if it's shut down).
 
I have all EPs except Bon Voyage, and I have the Glamour Life SP. I really don't want to have to reinstall, because I share my computer with Neuromantik and we're both in contests at this time.
 
Any suggestions?

deleted groups.cache, accessory.cache and cigen.package?

those three are usually the main reasons for my bodyshop/game not starting.

It worked!
 
Watching on task manager, it seemed like those files were causing programs to use more CPU than I have (as in over 100% of it), and that's what was causing it to shut down.
 
Thank you!

Actually, those files get corrupt somehow.  

I think you're the first person to say "I only did such-and-such," so that might help us track down what does it.
