DB Error when running model

When opening or running model, you may encounter one of following DB corrupted errors. This error can often be resolved by performing normal server shutdown via menu Help / Shutdown and then restarting the server.

 Failed to save execution stats to DB: IO Exception: "nio:C:/TestOptimal_Install_Dir/h2db/statsDB.mv.db" ...
 File corrupted while reading record: "nio:C:/TestOptimal_Install_Dir/h2db/statsDB.mv.db". ...
 The database has been closed [90098-200]

If the problem persists, you will have to replace ../h2db/statsDB.mv.db with a fresh copy of the same file from the downloaded TestOptimal installation zip file.
