If there's definately nothing preventing you from accessing Steam's servers you could try deleting the client (basically delete everything in the Steam folder except "steamapps" and the Steam .exe. Then launch from the .exe (not from a shortcut) and it should re-download everything from fresh (just the client stuff, your games will remain untouched).
