Rhythmbox: nothing work!

Im on 12.04 LTS Rythembox WILL NOT Play Streams...Last.FM WONT LOG IN...CANT listen to no music....I have no idea what your talkng about FRESH USER... Never knew I was a USER...10.04 Never gave me this problem.. Streams had always worked..Now my saved streams will not work...I never had to log into anything to listen to my streams I enter them into URL Add OR try to play a saved stream... It gives me an Error Sign When I click on it I get the following (This when I click on any avalible Stream Both from Ubuntu and Myself): Cannot resolve proxy hostname (), Also in a box on the bottom right of the window I get this: Unable to retrieve artist information: This information is only available to Last.fm users. Ensure the Last.fm plugin is enabled, select Last.fm in the side pane, and log in..... I never gotten this message or the other messsage tell now....Is this enough info??? Is there anything else I really need to tell you???...And far as what it should do instead? the complete opisite of what it is doing noted above...
