Epic client fail !FUNNY! >>MUST SEE!

It says I need 16 champions to play ranked and I do indeed own 16 champions I counted them a lot. WHY is this happening? The option to play ranked is also not locked. It's just when I choose it and press launch it gives me this error. Screenshot of error: http://puu.sh/tonES/dc80105ce2.jpg screenshot of owned champions: http://puu.sh/tonGT/b2fe29ef7e.jpg
