iFly 737 NG issues

[W4TT3RS]

I recently bought the ifly 737NG series of aircraft as I seen it was compatible with FSX:SE. I installed it following all the right steps (I think) and I loaded the aircraft up to find that it had no landing gear, as if it was invisible as the aircraft still acted as if it was there. If anyone has had this issue or knows how to fix it I would be highly grateful. Thanks!
