game freezes in when setup is clicked on

[Amazing Rando]

hi everyone, i recently bought JKII and the game runs decently(for a computer with a RAGE PRO TURBO graphics card) but when i tried uploading mods i ran into a very frustrating problem. In the main menu, when i click on setup, the whole computer locks up. i can access setup when im in the game but not in the main menu. I have a Pentium 3, 4+GB free HD, and 128 RAM.

 

Any help would be greatly apreciated,
