Fsx Captain Sim F/A-18D Problem?

I bought the xload pack and the nighthawk runs fine, but the f-18 has a problem. the two tails and the elevators are not visible, along with the 2 rear landing gear. it can fly and everything but it is just annoying me considering that i am going to be flying this aircraft for VNF. Could someone tell me how to fix it or where i can find another good F/A-18D as payware or freeware.
