Hi everybody!
I’m an happy owner of Cubase 6. Recently, I’ve purchased an Avid Artist Mix control surface.
The point is that it worked for just a month (maybe less), then suddenly one day a strange message showed up saying that my license for the surface was about to end.
Really strange… after this period of time, I haven’t managed to use it anymore, since the device stopped to be listed as a “remote device”.
The truth is, that I had done something wrong at first since I did not register the USB eLicenser key on MySteinberg site (but I did the activation procedure locally on my eLicenser). However, a week ago I correctly did this and now, on MySteinberg page I can actually see 2 products correctly registered (Cubase 6 & Eucon), but the surface still seems not to be recognised by Cubase at all.
I have two computers, one with Windows 7 64 bit and another one with Mac OS X Snow Leopard. I’ve updated everything, starting from Cubase (I tried with either the 6.0.3 and the 6.0.4 patch), installed the EuCon Adapter 6.1 (and of course drivers & firmware for the control surface).
I tried to contact by email the technical support, but in 3 weeks nothing has changed: they refused to give me another license, because they said there’s nothing wrong with the licenses.
I tried also to contact Avid, and they said that there’s probably a license problem.
As an extreme solution, I’ve tried to install everything from scratch on a new machine (just to remove any doubt that my OS/software environment was compromised): it did not work 
I hope that you can help me solving my problem, because I’m quite annoyed by all this stituation.
Thank you guys,
Giacomo R.
