Hmmm, I'm really not sure what could be going on. I think it would be best to leave it to one of the devs to help, any further input by me would just be random suggestions off the top of my head

. It does work fine with windows 7 though, also I've just been playing Automation for the last hour on Windows 7 compatibility mode.
Anyway, I don't really have anything more (of any real value) to suggest now, besides running the cleaner tool and maybe reinstalling. There's no guarantee this will work however, but it's worth a try!
Good luck!
