Lost all of my champs

Hi people I logged in a few minutes ago, and noticed that i couldnt see the champ rotation. Upon further investigation, i noticed that i have no champions. At all. Im not able to play any games, and I cant buy any champions because "this content is already unlocked"... but Im unable to play? I have repaired the client and logged out/in again a few times, but to no avail. Does anyone i know what i can do?
