[Newbies] transferring .image from mac to pc

[jacob remin]

hi all,
im having trouble transferring my work from mac to pc (running XP).
as i understand the .image and .changes files is all i need, and they 
should be identical on mac/pc/whatever, right? only the VM changes.
i've placed the .image and .changes files in the same folder as 
squeak.exe. when i drag the .image to squeak.exe i get a "Squeak fatal 
error". crash.
i've done the mac work in squeak 3.7.1, and so i've tried to import the 
work on the pc both in 3.9 and all the 3.7 versions i have found on the 
ftp. same error.
am i doing something wrong?
below is a copy of the error msg and the crash.dmp file.
cheers,
jacob
