Well, I've retried the mission, re-installed the game.. - i did that because i was desperate -. Also, the patches don't seem to work either.. might be a crappy disk. And here's more info that might help: When I start the campaign it has an error up in the left-hand corner, and it sais bin\config.bin/Worlds.West or something, does it with East too. For the patches, it just sais something about xdelta3.exe, and has a bunch of errors, no add-ons. Can't use the editor, I can make the units and stuff, but when i use 'preview' it just sends me back to the editor. Loads of bugs with this.. might take the game back and get ArmA 1 it seems to be less buggy.
Edit: For the Endmission cheat I was gonna try that, but I don't have a numpad (laptop) and way I can change it to another key?
