All my machine/game states in both MESS/MAME are grey. I've cleared caches and used Check ROMS but doesn't seem to be looking in the right location for them.

I definitely have the correct roms in c:/MAME/roms, and the working directory is set to c:/MAME in QMC2. Starting any game with a grey state works perfectly so mess knows where to get the roms but QMC2 doesn't. With MESS this also means that QMC2 doesn't read the software lists.

They were all green a few days ago but obviously some configuration option has changed but have been unable to find what it is. Help!
