My apologies, just discovered something went wrong when i downloaded part 4. Got a 4MB sized file instead of 40MB. After 2 tries installation was successfull and is now working perfectly. Please remove my previous post.
If you have trouble running this mod with a different language version use a registry editor search "Dangerous Waters" settings and set the variable aLetter to "e".
Thanks you guys a lot for this great mod, finally i can make the missions i was having in my mind all the time but couldn make coz of a lack of units.
