Make sure your firewall and/or router isn't blocking the game.
Cannot use this add-on in demo mode
Delete Cashe.DB and key.dat, then verify local files on Steam
I don't have a key.dat, but I did delete the cache, and then I verified the integrity of game cache.
There's your problem. The Key.dat is supposed to hold your key. I suggest move away your Base and Add-ons folder, launch blockland and let them re-generate and see if that fixes anything
If you have a steam installation, you don't have a key.dat (since you don't even have a key).Have you tried Restarting your computerChecking your firewallChecking your anti-virus (it may block blockland)I can't think of anything else right now that may be preventing it from authing.
