cannot log on with steam

I have been playing for quite a while but today logged on for one session, but when I tried again would not log on via steam

Not that this fixes your problem, but you don't need Steam to play TLD.  Just find it in your steamapps folder filed under "TheLongDark".

junglegreen - do you get any errors? When you say log on do you mean Steam won't let you log on, or Steam won't let you start the game?
