I've done dozens of Nevo configurations using 3 different PC's now, and have never encountered this issue (or any really, the software has been pretty flawless for me, after getting used to the GUI.

Sorry I'm not any help, but just wanted to give you a response, so you know this isn't something that happens to everyone.

Have you tried calling UEI?

btw, you mentioned that an error message pops up... what does the error message say?
Also, what OS are you running?
