Everytime I try to login to the PBE it says the username/password combo doesnt work....any reason for this? I thought maybe my main account wouldnt work with it or something so I made a new account and it still wont work...

Did you make a specific PBE account or are you trying to log in with your normal LoL account?

Yea I downloaded the PBE, and in the launch screen it says Server: PBE Open
I just cant log in

nvm got it working.... weird

What was the problem? I get the user/pw invalid with my account
