Forget the naysayers ... Omen2 is a grand addon in my opinion.
I have run into a problem, I have had to switch to a computer that uses Vista. Omen worked for a week but seems to have disappeared.
It shows to be installed, I can check it in the addon list, etc. It just doesn't appear anywhere. I've tried using /omen config, etc. to bring it up but nothing has happened. Any suggestions?
