I do also have a similar issue with my (black-faced) UX1. The problem is that my serial number doesnt work. I bought it at thomann.de/se which is a legit site. Everything went smooth until it came to the point where I would write down my SN. instead of the UX! it says on the box that the serial number should have PS1 in it and i dont know why. Ive tried both and no one seems to work it just shows me an error message which says "ESN could not be verified. Please confirm the supplied USN".
I need help ASAP.
