Dif works in windows but crashes on a mac

I have a dif file that works perfectly fine on the windows version of torque , but as soon as I add it to Torque on a mac , it crashes .I'm using Torque 1.5.2 and I've tried it both on a Intel and a PPC mac , and it crashes on both . I've searched the forums but didn't come up with anything . Anyone have any ideas about why this is happening ?
