there's a file in the ZIP called tools.zip. Extract that one and you'll find the MDB file.
If you're a first time user I'd advice you to go to http://www.snitz.info and download the Access 2000 database and use that instead of the Access 97 database that comes with the Forums. It's a bit more stable.
Well I meant if it's the first time you're going to use those forums It was pretty obvious you were going to start a fresh forum so my comment was a bit out of place. But look, now I can post another message without making it look pointless
Anyway, you're welcome and good luck with your forums. Don't forget to show off what you've accomplished when they're done
