Unable to login more than one user when set up for multi user.
Legacy KB ID: 238
When I try to log into the data file after entering the QuickBooks User Name and Password and clicking OK the LogIn screen just reappears with no error message.
This only happens when somebody else was already logged into the file.
This occurs when one computer has QuickBooks PRO 8.0 installed while the other has 8.1.
Go through the Help menu and select About QuickBooks, this will show you which Version is installed. Do this on each computer and any that only have Version 8.0 installed will have to be upgraded to Version 8.1
