Couldn't open table 'MSysAccounts' in SYSTEM.MDA.
This operation requires the SYSTEM.MDA file, which contains the security and option settings for Visual Basic database tables.
The SystemDB entry in the [Options] section in the .INI file points to a network drive that isn't connected. Check to make sure the network drive is available, and then try the operation again.
The SYSTEM.MDA file is corrupted. If you have a backup copy of SYSTEM.MDA, copy it to the location specified in the SystemDB entry in the [Options] section in the .INI file.
