PLEASE HELP, I'VE TRIED EVERYTHING!!!!!

So, First, I came home, started up LOL mac client, icon started bouncing, then the patcher icon started bouncing, then it stopped and nothing happened. Waited a bit then clicked the launcher again, Error saying one was already launched, do i want to terminate the old one. I clicked ok and it repeated what happened first. Went on the web and found information regarding deleting kernel in the systems folder, did that and pasted a new one from the DMG file. That didn't work (Yes i dragged the Launcher into the Application folder, and no i don't have any old LOL files on my computer left). Then i tried to just wipe out everything, and re instal client, and now its not even installing. The Launcher gets opened, patcher gets opened, bounces for a bit then nothing opens. Help????????
