Also make sure that you're not using any anstispyware/security that may be stopping LW from opening. Some will see LW as a threat (it's not). Make sure LW's on the list of exceptions/allowed apps for any such programs.

well, it doesnt come up as blocked, if it did i wouldnt have been able to download it in the first place, just what happens is it starts with the preloader menu, then quits, idk why, but ill try what you said, the farthest it gets in the preloader is loading library menu or something like that then it quits
