Bridge TuFa mission = Fatal error and Douglas AH-1 Black pr

Hello,
Have downloades the A-1H Skyraider Navy Va 25 and Va 176.
1.The 176 works in free flight but the Va 25 in virtual cockpit has no outside view (all is black)and switching to outside view you can see a black propeller. Why, both planes are on the same download.
2.Concerning the Bridge mission it loads to 100% and after a
"Fatal error"is shownl.
All downloads have been executed correctly and Acceleration is installed.
Only one forum says you have to download the chopper A-1H
Did not do that because it is not mentioned in the download instructions.
thanks for answers
