Hi.

I was just wondering if it is still possible to unlock 0.5P given I managed to redirect LFS' unlock-call to the current master server (i.e editing my hosts file).

If not, what is the oldest release that is unlockable?

I believe you can still see the master list with this one, but cannot unlock:

Edit: Just got LFS S1 0.3H6 unlocked and working on Multiplayer.

Can You pls say something more as i'm getting unlocking error?

Make sure you have LFS S1H, then you need "LFS 0.3H6 - Patched.zip" from http://www.lfsforum.net/showthread.php?t=22662.

Once you download that, unzip the patched LFS into your LFS 0.3H6 folder, and start the patched LFS. Then unlock. It worked for both of my accounts.

Edit: Currently hosting a server called "LFS S1 0.3H6"

Well i did it and got error i already mentioned :/
