Hi i reformatted my hard drive  just to get nexus radio 4.11 working but the software is messing up for me an most vista users about 500,000 of em perhaps more.  Nexus does not  knowledge the problem and give complicated answers   that they f*** up.  but they do not admitted  anyway here are 2 solution roll back to nexus version 4.0.0 which worked for me or get the  portable version on the web. 

let me know if this works..

Thanks Steve.
