Hi, im new to ArmA and i downloaded your mod so i can use it with the Croatian Armed Forces mod. I decided to start in the Editor, and spawned in a Mi-171 helicpter. That worked just fine. Then i wanted to try out something else and chose the Patria AMV, and clicked preview. The map started to load but then the game crashed and i got an error message saying :"Bad version 68 in p3d file 'mas_us_rifle/mas_m4.p3d'. What might be causing this problem and is there a way to fix it? If there is a way please explain it to me because i really want to play xD Thanks in advance
