Torque doesn't recognise new directories.

Hi,

I've created a variety of new folders in my interiors folder, with plenty of textures and DIFs inside. However when I go into mission editor mode on torque nothing appears in the directory tree to the side, just the default ork village huts and dock stuffs (still on 1.4 here). I've tried reinstalling Torque which didn't help, it seems that nothing new I can add will show up, or be recognised. Any ideas?

Thanks,
