Sorry I managed to fix it myself. After an hour of trying to solve it I tried to launch it as administrator showed em. Should have tested that before I made this ;(

<t> Hello,<br/>
<br/>
I have installed the community pack for this game. Though when I launch the game and press "new game" only the native 5 campaigns show up. I have checked and the mods are in the "campaigns" folder. I have no idea why this happens, I have the newest version of the game as well ...
