Yes, I got the same thing. I got the message on my email that I have successfully unlocked LFS S2, but ingame it says ''unexpected size packet'' as well as still states that I have demo user ingame.
Please help.
It's very simple - some people will be thankful for the support LFS gives therefor it will attract MORE people into the community! That's what we clearly need, we need more recognition and this is what will give that recognition.
