Q: I get a message "...Unrecognized database format..."

Open the datasims folder (on server or on the C:drive)

Double click on the file simsdata.mdb.  Access will then inform you that the database needs to be repaired.  When
it asks if you want to attempt to repair the database click on YES.  Leave the program to do the process.

When this is done the tables will appear on your screen. Close all the screens.
