I have an account on PBE but everytime i open the lol.launcher file that I got, it makes me reinstall the game. I don't want to have to wait an hour to play everysingle time I want to. Help please!

do you have deepfreeze? did you extract the contents of the zip file?

same thing is happening to me as well. i extracted the files and downloaded the huge patch and played a game, logged off, and tried to come back on earlier only to find i have to wait 1-2 hours because i need to redownload a patch it supposedly already downloaded?
