Hello everyone I just bought a Ux2 (second hand), I already downloaded the drivers from the line 6 page. I actually downloaded them twice. One directly from the line 6 page and another round from the Line 6 Monkey software. Well the thing is when I go to the Licence Manager on the Devices section appears my Computer (authorized) and then my UX2 which appears unauthorized. When I hit the authorize button a message appears me that says: "Error attempting to authorize your device. Code 80000002 Invalid Parameter" I also tried going to http://line6.com/account/registergear/ to register but another message appears: There was an error processing your submission.ESN could not be verified. Please confirm the supplied USN. ( Error: 523) Can anyone help me? :) Thanks in advance! I'm an avid line 6 user who had owned many of their products like spider jam, spider iv (halfstack), dl4, m13, echopark and g30.
