System restore will generally break your install.

A Reinstall following this guide, http://support.leagueoflegends.com/e...gue-of-legends should clear everything up.

i also can't login to the pbe

Omg, you saved my life, literally! lol Thank you sooooooo muchhhhhhhh

My League of Legend has been messed up for the past two days, every time I try to get on. It has an update but after its finished the white numbers go into the negatives. I tried asking my friends to see if there was an update but there wasn't, I don't know why for me it does. I can't even press the play button, can you help me?
