Hey!
I fixed the problem for my self by just deleting every file in RADS folder which is inside LOL instal directorty. Every log and versions file must be deleted and then it will launch good.
You like erasing all things, don't you? Because your method is a bit extreme... And this is only a work-around (by the way I don't know how you managed to launch LoL without the rads subdir, which contains the core launcher), we are trying here to _resolve_ a bug in Wine.
