HaloMods "Classic" Read-only Archive

I have just recently gotten mimesis v3 and ever since then my halo 2 maps don't load. Also my disc doesn't work. They worked fine with mimesis v2 but not any more.
I also re-installed my au and tooken clean halo 2 maps from the disc and put them in my hard drive.
Could I get some help please?

sorry if this is in the wrong section

Usually when even the disc won't work it is a cache problem.

Clear out E:\CACHE\;
X:\;
Y:\;
and Z:\ directories.

Then try and load Halo 2 again.
