TOPIC:

Whenever I try to open the game, I get this error:

Invalid version on pack file store.pf (0)

This is the whole info:

** Error Information
etrace: Invalid version on pack file store.pf (0)
Module: pack_int.c
Line: 427

Does anyone know what this means? Any help would be greatly appreciated.

I'll just delete the game and re-download it. That will most likely help, because something that I downloaded for the game is messin' it up.

Yeah reinstalling should fix that. Sounds like you just got a bad download. It happens.
