Hi,
you may find that it is the version of windows you are using. I used PC2Amiga on my 1200 to a Win95 PC a few years ago and it worked without problems.
I do remember reading a review somewhere where it was mentioned that the PC prog needs to be run in a DOS window, ie dos compatability mode in XP.
It just may not work with newer versions of Windows which is not surprisiing when you consider when it was last updated!
