Bob,

Make sure you have done "DO MAIN" in debug mode (DEBUG.TXT) so that your metadata.dbf is completely up to date with all the latest classlibs etc. Double check to make sure the metadata.dbf that is distributed in your EXE is the correct one. Have you tried running the EXE on your machine after renaming your dev folder(s) out of the way to see if you can get the same error?
