I'd like to help and I'll see if there's anything I can do with the mdb/mdw you supplied but I'm having difficulty even getting into the mdb with the mdw you supplied. Keep in mind that Access security is NOT easy to crack, especially on mdb's which were created in older versions of Access. I was able to crack a protected 97 mdb which was uploaded in a thread a few days ago but I didn't have problems with the mdw file like I'm having with the one you supplied. I don't think you've supplied the correct mdw.
Please answer these questions:
When you get into the mdb, are you able to go to design view of any form or does it tell you that you don't have permissions to get into design view?
Are you able to get into design view of the tables?
Are you able to go to Tools -> Database Utilities -> Convert and convert the database to a later version of MSAccess?
What version of MSAccess are you currently using?
Did you try getting into it and exporting all the objects into another new mdb?
Did you try importing any of the objects into a new mdb?
If you select Tools -> Security, what options are available for you? Have you tried adding a new user if available? Are you able to edit the Admin user?
Are you able to run the wrkgadm.exe and join to the mdw file?
Are there ANY other mdw files on the drive anywhere?
Did you create a new mdw (DON'T)? Again, I think the one you supplied is not the correct mdw. See if there are any other mdw's anywhere which might be related to this mdb. If you somehow replaced the current mdw with a different one or somehow created a new one, you need to let me know. You may need to restore the mdw before you created a new one. The mdw is extremely important and holds all the security information for the mdb. Creating a new one or copying one from another source can make it futile in breaking the security (and lock yourself out of the mdb which is very easy to do!)
Upload screen snapshots in a zip if you can. It will really help.
Otherwise, there are companies you can search for on the web which specialize in unprotecting mdb's. Cost I believe is around $100 or more (but don't quote me on that.) They may also need the original mdw file though. I'm trying to help you free of charge but I need you to try a few things.
