[Client]- PBE Client won't open after installation.

PBE Client don't open after installation. I just run the PBE as the normal client. But then it just appear the "League Of Legends" logo or a couple of seconds and nothing more. I have already checked everything i could. No background processes open after that passage.

1-Run the PBE client. 2-"League Of Legends" logo appear. 3-Nothing more.

Someone have a solution or have the same problem?

Ps. Sorry if my english is bad
