I have no idea what is going on. I can play sins normally and all yet when i go options -->mods then i click a mod (BKGM for instance) and click the "load mod on startup" nothing happens. the box doesn't get checked or anything.

*sins is patched to 1.05*

also, if i try to click enable mod (inorder to click the "load mod on startup" the game crashes so there is no way that I can enable the mod

please someone help, if you need additional information, I'll be glad to answer your questions
