May I ask why you aren't using the Mac version?
Are you using the Modern or the Legacy app? Also, I'm almost positive someone reported this issue months ago, and I fixed it in one of the 3.201 versions. There should be a log file outside of UWUVCI that's in the app itself. It's a WINE log, that will have the actual error message as to what's going on. I don't remember where it's at, and I'm replying to this away from my house.
