Hi, I bought Crysis, Crysis Warhead, and Crysis Wars in a pack on sale on Steam recently. When I first bought the game I started a game on easy and a few minutes in decided to start a game on Delta to see what the difference is. I then wanted to go back and make a game on normal, yet when I play it, it's on Delta Difficulty. I have tried numerous times to start a new game on all difficulties, but it always says delta in the options. I know for a fact it IS on delta from in game things as well (enemies speaking korean, dying from 3 shots etc.) and when I try and load my game on easy It crashes saying Crysis.exe has stopped working.

Thanks in advance for any help.
