Hi, i'll pay for unlock the S2 LFS, and i've got some problems, whith my windows, and i can't unlock it now, please something can you help me?????

Why can't you unlock? Is it not working (if so, what happens) or don't you have any unlocks left?

If you have no unlocks left send an e-mail explaining the problem to the developers and you might get an extra one before the month is up - http://www.liveforspeed.net/?page=mailus
