IT WORKS! YES! THIS WORKED! THANK YOU :)

Nope, didn't work either... :(

JStewart: Any ideas?

I will try this, thanks :)

Unfortunately this didn't work, any more suggestions?
I'm getting a bit desperate...

Checked that, not that either.

I only have a single hard drive. What I don't understand about this problem is that it all worked fine before but since the 0.55 Experimental-Stable has come in nothing will work.

Yes, indeed I have. Both various times, I've also tried running Steam as Admin, launching the game from Steam etc.

Ok, I've re-downloaded the game and I basicly get the error http://gyazo.com/5e1855b9e993258b3107951e34c79261 from here, any recomendations? Try and start fresh :)

Yeah I tried this and the issue still persists. I'm a bit worried there may not be a solution?

JStewart: No I did not. If you want proof I can give it to you but I promise that's not the case, otherwise why would I ask for help. Any more suggestions to help me? Because I want to play the game and like I mentioned, would a new game/code help this?

trujuice: Where do I go to access this parameter? I wil try this

Nothing happens. It only happens if I launch from Steam. I've tried other things since my first enquiry and still nothing even though all the other games in my library work. I'm thinking only a new game can fix this? Because I've re-isntalled Steam, DayZ, I've changed settings, deleted AppCache, etc... I honestly believe my game is non-functional or has got infected or something...
