Cannot download or update any app in BBW

Some days ago started this problem (which I have read that is happening to a lot of people) with my BlackBerry World and now I can't even change my username in the settings menu, download any new app or update an app, is there any solution?

Thanks!

There is actually a search button on top ;)

I searched for it, but didn't find anything to fix it or relevant information. The other problem is that I can't even download the update for BBW :/
