Bing maps on windows phone 8.1 lumia 525 not working

[aerosidinc]

Everything was fine but suddenly Bing maps has stopped working. It doesn't load map data. It just shows my location indicator and blank page,no map. I can not even check for map updates and offline map also not downloading. Though I ve working internet and everything is working fine
'check for map updates and download offline" keeps on loading forever and says cnnt connect to library. Moreover when it used to work my current location used to be inaccurate and moving here and there within second.
