Ok, I a fixed it with this Emergency file
Before you install go to "\T34vsTiger\Missions\Campaign_1\Mission_1" and delete the contents of that folder (all files).
Then Install this:

PS: It is vital you delete the files in the folder manually because I mixed the files when I accidentally pasted
two mission_2 files in the wrong folder
