issue:I just bought and installed File Maker Pro 6
"won't let the user into the file" means that they are getting a password dialog that they can't get past?
Or does the file close or FIlemaker crash when they attempt to open the file?
Do you have a backup copy of this file?
Frankly, I'm amazed that FileMaker 6 works at all in WIndows 7 given the extreme age of that version.
