HaloMods "Classic" Read-only Archive

I've been using the devmode on HaloCE for along time.And suddenly it no longer works.I typed -console -devmode -window
It loads up HaloCE,and before it gets to the title screen,it says the exception error.
Is there any way to fix it?I want to know before I have to re-install HaloCE again.

I dunno... there might be some sort of shortcut error, but generally the exception error comes from when the game is looking for a file or piece of code and it cant find it. check your files in the game dir and replace whatever needed, or just extract those cab files off the cd, and replace stuff like ur dlls, maps, and haloce.exe, and such... and check on your ce version.

mostly this would happen in ce becuase of a custom map...
