Hi ChessMaster,
Welcome to the Forum.
If I remember correctly from when I used to use my ver6.52, the problem you describe comes about when you delete/move a data directory or its contents after previously accessing that folder/file and you have Tools > Options > General > Restore Workspace selected. In this configuration, MS will remember what the workspace looked like when MS closes normally (crashes have different effect). The next time MS starts, it will try to open the same data files as was open the last MS was used, so if you have deleted/moved a data folder/file, MS will get "lost" and errors are generated.
Hope this helps.
