Here are a couple of things to try: first, take out the CD-ROM before
starting - you will probably get a "critical error" message, that's OK,
just hit 'I' to ignore. That will keep the intro movie from trying to run
(a lot of systems have trouble with that). If that doesn't do it, go to
the MS-DOS prompt (within win95) and try running it from there, either by
typing N2 or NASCAR2 from the \sierra\nascar2 prompt. If you're getting an
error, you should be able to see it instead if it just flipping back to the
desktop. If you're getting an 'unable to start screen - possibly out of
memory', then you've got corrupt data and will need to reinstall.
Hope this helps
