Unable to download from **** 5

Hi guys,

I own an iPhone 4 and iPad 2..
Recently I'm unable to download any app from **** 5... Once I click on any app to download, the authorization page appears without any code... Thus I can't proceed further...This issue persists on my iPhone for nearly a week already...
But I do not face this issue in my iPad.
Both are running in 5.1.1(Redsnow)

I tried re-installing **** and **** but no improvements...
Pls advise...
