While waiting for the replacement CD and eager to get into CMBB I just tried a new approach. I have a P2 400, Win98, machine that we use for internet stuff (formerly my top of the line gaming machine and the home of CMBO for many months ); the CMBB CD, which will not run completely on my new "top of the line gaming machine" (well, it was for a couple of weeks, a year ago ), installs perfectly on the old machine; all files in all their folders, HOWEVER, (you knew that was coming) when I attempt to run the game up pops this message: "Unhandled exception; Unhandled exception: c0000005, At address: 00570100"; acknowledging this message results in: "This program has performed an illegal operation, bla, bla". My question: if I transfer the CMBB files to the other machine is there something inherent in the "Unhandled exception" message that makes it likely that CMBB will not run there also?
