HaloMods "Classic" Read-only Archive

I messed something up with my game pretty badly. When I go to multiplayer and to create a game, blood gulch is not on the maps list. I tried reinstalling it, and completly uninstalling it and reinstalling it but nothing has worked! Could someone please help me fix my game?

Try uninstalling then deleting the remains of the Halo folder then reinstall.

I found out what was wrong with it and blood gulch is on the list, but now it's in the wrong spot and when I try to connect to gamespy it says error connecting to the gamespy master server. Is this normal or is something still wrong with my game?

Did you install the update?
