Thanks for taking the time to read this and as a newbie I know its probably a easy one this but when I try to play music after pressing the play music app  I just get a message saying ' Music temporarily unavailable' 'Couldn't play the the stream you requested' and a Done button but no further info, I get exactly the same thing on my Nexus 4 and my laptop, any ideas lads and lasses ? Thanks. Peace.

Had my N7 for a couple of weeks now, its easy to use and great value for money, I am so pleased with it I bought an N4 which arrived yesterday, however I've already buggered something up when I changed the proxy settings in an attempt to install Adblock, now neither of my devices will connect to web and display the' can't find proxy server' message, can anyone help me, what was the default proxy settings on the N7

Thanks.
Peace
