Hmm, never had such an error message, is there an MSinfo file in the program? It might have instructions for a patch. If not, it helps to have the name of the group that err.... made your program possible; there are sites which store these MSinfo files by group name; haven't really dabled in this stuff for a while so maybe someone else can pm you the latest information. BTW, these programs usually come in a cd-image format so there could also be a problem with the .cue or .bin files. You could also have downloaded a screwed up program, happen sometimes on Kazaa. In that case, if you really want the program, try a google search on torrents or check out the IRC.
