I've been having issues the past couple of hours trying to get my license manager/line 6 monkey to connect to the server (error code 80001019) and recognize my UX2. Thanks to whoever mentioned Europe based customers having issues. The fix for me was to use VPN to reach back to the U.S. server. Somehow that fixed all my connection issues and I've been able to authorize my UX2 with the license manager, which gave me permission to use the UX2 with Pod Farm 2.5. The line 6 monkey also finally recognized that I had a UX2 connected all this time (it was defaulting to a POD NXT, which i don't own, before).
Hope this helps someone out there.
On a related note, has anybody had issues using a UX2 while having a HDMI output. I can play youtube/music/etc. but I can't hear my guitar, even though both the UX2 and Pod farmer registers inputs.
