Where are the wheels??

Well i've added this new fighter to my airplanes... upon selecting it i get this error that some elements might cause errors so i was asked if i would change them or smthin.... i accepted.... now the plane is always gear up ( when they're down u could use them but can't see them) also the fughter's hatch is always open ... can't close it...
tried deleting the files related to the plane then reinstalling them but still the same happens.
didn't try reinstalling the game though
what can i do??
