I'm not sure what is going on with Nevo, but I know that URC had a bunch of trouble getting codes to work with these new boxes.  URC actually has multiple codesets to try depending on if you are using IR control, or RF control with one of their basestations.   Since Nevo doesn't sell the Q50 to the US market anymore, we are no longer a Nevo dealer.  I don't know if their database is still being updated.  You might be able to use a URC remote to teach the codes to the Nevo, but I have no idea if that will work correctly.
