If you have a Arcserve Backup on Small Business or regular Server which is not running and you think all is ok from your side concerning, Updates, Patches, Permissions and the Device.
Then maybe the Database is corrupt. This happens with almost any Arcserve which was running over 2+ years. It's may simply get too big in size in this may be solved too.
Here is a standard script/batch to repair Arcserve DB errors. Check the account and password from your install doku. It's also possible to reset that password.
