It is typically because you have lost connection to your company server that is hosting the TATEMS back-end database file.

You can check by trying to navigate directly to your company server and the folder that is housing the TATEMS back-end database file called tatems2005be.mdb 

In windows file explorer try navigating to the server. 

If you know the path to the data file you can type or paste it into the address bar of the file explorer.  

Something like this 

\\ServerName\Folder Name\TATEMSData\

if you get a cannot connect then you need to have your IT person fix this issue.
