I don't believe uninstalling and reinstalling the mod is going to make a difference. Though it's certainly worth a try.
I think restarting your computer and using REZ Handler to disable more maps, then trying to run the game again, might have worked. The symptoms sounded exactly like the "too many .REZ files" problem.
Either way, good luck and I hope it works out.
Okay, I got it to work. However, I don't exactly know how I got it to work.
Now I've got another problem. It only works when I start it up normally through the Mod Manager, thus taking away all my controls.
And what's worse is that I cannot run the game through the Mod Manager in Administraitor Mode (to allow my controls to function)
So, in a sense, I went out of the Frying Pan and into The Fire.
