Well i figured out the problem on me and 6 of my friends side.
After reviewing my log file, i noticed it was a problem with All in Arma terrain pack.
I went and found a hotfix for it, https://mega.nz/#!EoQSnbaA!F32Lggg-V0bDfSeQQ-dMSIiZYiHx0l9uFsY1ThtTtSM
Replace your files with the ones in your current AIA TP addon folder, it works for me and all of my buddies so it should work fine for anyone else.
And the problem that you were having Chump is just because you had the wrong addons enabled, im sure most others dont have that same problem.
