Creations for The Sims 3
Yeah I did that once but compressorized EVERYTHING, sad times. Backing-up before hand would have been sensible.
Not sure what compressorized means but if its about reducing the number of package files that the game has to parse at load up, then yes I've just done that. I got about 1GB of cc including my sims3.pack files into 20 package files which now makes the game load much quicker. It was a little fiddly but worth it. Sorry you had trouble :)
This is why I back up my downloads in .package form.
