Thanks to all who replied, please be reminded that the error precedes the use of the mixer. I plugged the mixer in so that I could track down the USB information asked for earlier in the thread. My issue is trying to open RB without an error setting as I've done in the past. I should be able to click on the program icon, and the program open without indicating there's a problem. I'm getting an error before I ask it to do anything. The mixer is set as the output device in windows, but that hasn't stopped the error from appearing when RB is opened.

I do appreciate the assistance and will try to identify and track down as much as I can, vacation is over Monday so if this isn't resolved over the weekend I'll have to bug the hell out of the creators in my spare time.
