Help! Exception when loading maps

[seanthelawn]

Well earlier today, Halo was working fine. Then I decided I wanted to start a dedicated server, so I set everything up and started it. After that I tried to test a mod I'm making, so I started Halo up. However, when I tried to load the map, I got an exception. I figured it was something wrong with my mod, but after a while I realized I was getting an exception for any map in my maps folder (including default ones). What is causing this?

This is Halo PC and not CE?

If you just want to start fresh with new maps, you can try extracting the maps off your Halo CD.

They should be in your disk drive\FilesCab

Extract the cab files with winRAR or whatever and the maps are in there

No, this is CE :/ I'll probably just end up re-installing.

EDIT: Yeah, reinstalled and now it's working fine.
