HaloMods "Classic" Read-only Archive

I got a big prob... I recently started messing around with a few modding programs: Sparkedit and Halo mapping tools. Now the problem is, i started to mess with blood gulch and now i can't play it anymore... I know i shouldve made a backup and I know that I'm a modding n00b, but can anyone tell me what to do? I alredy tried reinstalling twice, but it didnt help....

Reinstalling should have worked. If your on vista run the game as an administrator by right clicking>Properties>Compatibility tab>Check run as administrator after you reinstall.

oh thx, that workd just fine
