i am trying to play shogun 2 total war and steam is telling me the game is unavaiable. I dont understand how its unavaiable when its on my harddrive ready to play. This is Drm failure at the moment when i have tried both online and offine and have got no were in trying to get it to work. My other games work so i will give them some love since i have been playing alot of shogun 2. 

did you update the game recently? have you tried restarting Steam and your PC?

i have tired restarting multiple times. Maybe it is updating i need. Well i currently have super slow net so i will wait a few days until it comes back nand give it a try. 

but updating shouldn't be the case, i want to play without updating required so that is a problem when i cant play the game because it needs updating and what happens if i have no net, i cant play at all.
