Please help fix my scheduler which hasn't worked in years

[bcometa]

this morning woke up to the all too familar "copy job" window that can't be closed (needs to be forced quit). Of the 5 drives that were supposed to backup early this morning, none did. This is exactly the same problem I've been having for years. So much so that I have an applescript to force quit the copy job window for me. This is a major issue with superduper imo and unless you know what is causing this, may cause me to completely abandon it and search for something more reliable. I hope you know what's wrong. *No log file available in console or SD, from what i can tell.
