3051 - The Microsoft Jet database engine cannot open the file '<file name>'.  It is already opened exclusively by another user, or you need permission to view its data.

This error is generated when WBSP engine tries to open MS Access database and Jet engine is not able to complete operation.
Possible causes:
- Your permissions in system.md? file are not valid for required operation. You must have permission to read data in the specified file in order to view its data. To change your permission assignments, see your system administrator or the table or query's creator.
- WhizBase does not have write access on the directory where database is located and was unable to create <file name>.LDB file. Assign WBSP engine write permissions over the directory where the database file is located.
