Unhandled exception "Specified Cast is not valid"
This error may appear on the Mentor which indicates that there is a corrupt data base file.
Mentor error “Specified cast is not valid”



The fix:

One of the databases is corrupted, either CBWProc.mdb, Backup.mdb or Miltron.mdb. 

The CBWProc.mdb can be renamed and Mentor started again to determine if this is the corrupt database.  If the error still exists then you can rename the backup.mdb file and try to start again. 

If these fail, contact Milnor Tech support for help with the Miltron.mdb recovery.
