What will happen if i try to unlock LFS on my parents computer?

You mean, now that we have the server problems or what?

If lfs is compatible with your parents, it will just unlock. If it isn't, the main hard drive will be reformatted.

Do you mean what happens if you have 2 LFS Games and 1 Licensed name on both Games?

What i mean is that i would like to be able to play LFS when i am at my parents...

Yes.
