RFEditPro Stopped Working

OK, so I tried to launch RFEditPro this evening and it just showed the RFEditPro logo and gave an error message, saying:
RFEditPro has stopped working. Now it won't launch, what could have possibly happened?

does the demo work?

If you mean the RealityFactory.exe file, yes it works, I have another RF copy in another folder on my PC, and there the editor works fine... The problem is that if I try move my game files to the other folder, the texture files will be messed up, then and then in the editor I'll have to copy the whole levels and paste them in new empty 3DT documents, but then I'll have to retexture everything again

EDIT:
ha...this morning it was working... strange...
