Yes, it is very difficult to understand you.
Here's something you should consider. Keep a personal log of EVERYTHING you do with your game. Here is a random example of one of mine:
Saturday 3:28 AM 12/11/2010...............................................................
3:28 AM 12/11/2010 Installed Reduced Airfield Radius in MODS folder. Tested/works.
4:58 AM 12/11/2010 Installed U2 SAS in mods. Tested and everything works.
5:47 AM 12/11/2010 Installed CSS13/U-2PO. Tested/works
Wednesday 7:36 PM 12/15/2010.............................................................
7:36 PM 12/15/2010 Can't get the Kraut 20mm flak guns to shoot in the ZIM mission. This may be due to the ground attack mod. Try making a new mission with that map and only have my plane and a gun.
8:34 PM 12/15/2010 Seems to work without the set the ground target function from the menu. Just put a waypoint near the target and the flak blazes away just fine.
8:53 PM 12/15/2010 changed the Zim mission but still no workee.
I guarantee that this will reduce your problems almost to zero.
Later,
