OK. I think I found the error details. I've gotten three different errors that all have to do with those "trunk" files. The errors are stated below:
Faulting application fred2_open_trunk_20080708_d.exe, version 1.0.0.1, faulting module fred2_open_trunk_20080708_d.exe, version 1.0.0.1, fault address 0x00166687.
Faulting application fred2_open_trunk_20080708_r.exe, version 1.0.0.1, faulting module fred2_open_trunk_20080708_r.exe, version 1.0.0.1, fault address 0x0009ace4.
Faulting application fs2_open_trunk_20080708_d.exe, version 1.0.0.1, faulting module fs2_open_trunk_20080708_d.exe, version 1.0.0.1, fault address 0x001a6247.
I've got this feeling, though, that I may have missed a step on installing the mod. Hopfully this is what you were looking for.
