Giri giri running problems

I currently have 3 games to test,
sega rally and shining force 3 as ISO's
and Chrismas nights actual game disk.

When I try to load an ISO (well, cue file thingy) the saturn menu always says 'Disk unsuitable for this system' no matter what region of game or emulator I try to use.

When i try and load my (europe) christmas nights disk, giri giri comes up with an error (unable to read TOC) which im guessing is table of contents, and closes.

Everything else, like the saturn menu's run fine.

I've been trying for days. please help!!

Thanks

Ok! So, i found the TOC file, but, now, when I tried to load Shining force 3 it told me to check my CD lens or something? Gah!
