Beta Client Update Bug

Dear Riot,

so i recently updated the Client to Beta. It worked fine and everything looked good. Then, the Anivia Skin was updated into League and scince that Patch, the Beta Client won´t start and instead shows : "League of Legends has encountered a Problem. Please re-Install League of Legends alpha client to try again." So i reinstalled the Game and started it with the alpha Client and got the Game to Load up. Then again, when i tried to Update to the Beta Client, the Error appeared.

I will now reinstall the Alpha Client. Hopefully this Bug gets fixed before the Client gets exchanged.

Thanks in Advance KillerRatte
