I have a access 2000 database the has user level security (mdw file). The file is accessed by 25 users daily. For some reason, this morning the file will not open. The mdb file is smaller (down from 3.5MB to 2.6MB). I get an error when I try to open it stating "Unrecognized database format". Compact and repair will not work, I get the same error. I can't export, same error. I am a network admin by trade, but I was volunteered to recover this data. It was not backed up. Any suggestions on how to recover the data would be greatly appreciated. I have no knowledge of VB...I've seen some articles about using it to recover data but they are over my head... Thanks!
