Just a quick question about the unlock system. When I dont play the game for a little while I always seem to have to unlock the game again. I haven't reformatted or re-installed the game, or do you need to unlock after a patch?

You need to unlock after a patch sometimes. I think?

The only recent patch that caused the game to lock was patch V, the myriad of test patches before its release didn't do that. If you get regularly locked out, using hibernation mode could be the problem. Other than that, no, getting locked out of LFS is a very rare occurrence (I think patch V was the first time I had to re-unlock since getting S2).

Only after some patches.

If you didnt change anything after your last use you shouldnt have to unlock it again.

Ok thanks for the swift responses, much appreciated.

I think I had to unlock the game again after Windows reactivation.
