I have to agree, you have a nasty problem and none of us are able to help you it seems.
Still, I'd advise you not to quit so easily.
Put your ROMs in Project64's Roms folder (unzipped) and see if they pop up on the Rom Browser after you've started the emulator and pressed F5. For the record, most common extension for N64 ROMs are .rom, .v64, and .v64, but there are others too.
