Ah, yeah, BLCMM's intended to manage mod patch files, not the main EXE itself. Still, it wouldn't be a bad idea for the app to notice that a user's trying to open the EXE and fail more nicely. I'm reopening this and will put in some extra checking on file-open actions. Cheers! Thanks for the report!
