Beyond:
1. Have you tiried uninstalling and reinstalling GE? I know that this is a simple fix, but in the past, I've found it has worked for me. Personally, I've never had any issues running the programs on my PPC (ViewSonic).
2. What sort of PPC do you have? Maybe you do need a different bin from those that you have tried. I believe that there are several that Makslane has developed for users of non standard PPCs.
I have a feeling that Makslane may need to answer your question.
