Chances are someone had been there before you, open doors is a sure sign that someone else had been through the area.

Both are known issues.

MrSammers, I remember reading a post somewhere, did have a quick look for you, but unable to find it at the moment unfortunately.
But it read something along the lines of, you will need to contact where ever you bought it from (Steam or the Bohemia Interactive store) and ask them.
Personally I do not like your chances as there were adequate warnings about the game from Rocket before you where able to purchase.
Best of luck on your venture..

DJshotzz504, as R834 stated this will be the cause, open doors everywhere is a sure sign people have been through the area.
