"Update Failed" Log In Issue..

So recently, as we are all aware, some of us have been having to log in twice to play LoL. Well now whenever I click my LoL shortcut icon to open up the game, I get this "Update Failed: Unspecified error occurred. Please check the logs for more information". I'll hit continue but then the sucker doesn't move past 0% or past Calculating differences: 1 files scanned. So.. what's going on here?
