LMS Perfect World

When I opened LMS, the update window popped up and out of habit I clicked okay, automatic update to LMS 1 (I think it said that, at least). It finished updating, I guess you can say. When I clicked start it wouldn't launch any more. This is the second time that is has happened and the first time I re-downloaded the game. Should I do that again and whenever that update window pops up again, I should ignore it or is there an other way to fix this without re-downloading>

If this happens again, try to do this.
Go to your PW folder, there's a file calls startclient.bat
Double click on it to launch the game.
