I can't open the patcher

I click on the lol.launcher.admin.exe then appears the lol logo, and closes. I can't even get to the patch EDIT: i even downloaded the pbe again, but it's the same, just creates the "logs" folder, and closes itself. EDIT2: My latest [log](http://C:\PBE) My install path for the pbe is C:\PBE EDIT3: grammar
