I dont know if anyone else has asked this since im too lazy to look.Iv never played any of the thief games before and the new looks really good.Are they all related story wise?Because id love to play the new one when its realeased but id like to know if i should play the old ones first.

I reinstalled and now its working thanks for the help. :)

I tryed uninstalling then reinstalling steam but now I have to reinstall all of my games.Is that supposed to happen?Or am i just having a very unlucky day :(

I tryed what you sayed lostrib but now its says that i dont have a valid steam subscription for that application.

Tryed that and it didnt work.

Yes,thats where i start the game from.

I do have steam.

Iv been trying to play Rome total war however whenever I try to open the game it says "failed to find steam".Anyone know how I can fix this?

If i buy a game on cd key warehouse can i register it to my steam account?

I just got the Arma 2 complete collection and dowloaded dayz.But it wont let me play dayz everytime i try to join a server it either says bad version or says waiting for host and never loads.
