Invalid command line. Unknown switch 'connection:user'.

Invalid command line. Unknown switch 'connection:user'.

I've been using dbforgemysql in Windows for manual backups and decided to automate it after a recent server crash at our ISP. I've followed the directions, but no matter what I do I receive an error. Invalid command line. Unknown switch 'connection:user'.

dbforgemysql.com /backup /connection:user Id=xxxxxxx;host=xxxxxxx;port=3306;database=CMSC;character set=utf8; /projectfile:M:\Windows Docs\Devart\cmsc.backup

Is this not a valid option in the studio version?
