Do you have the bitmap files (saved as Windows bitmaps, i.e. .bmp files) in the folder for the game system, named "tech.bmp" and "jam.bmp"? (The file extensions are important.)
If you do, everything should be working fine. If not, make sure they're saved in the correct format, with the correct filenames. If that still doesn't work, please use CVExport to package up the files, and email them to me at
colen@wolflair.com - I'll take a look at it and see what's wrong.
Hope this helps!
