Hi TigerTwin,
For the solution to the bouncing, please go here:
http://www.flight-replicas.com/Downloads.htm There are instructions there, but if you need help installing, just get in touch with me at the support address in the J-3 Manual.
As for the textures not showing, this is usually due the graphics card not being up to the job (the J-3 has high-res textures), or not using FSX with either SP2 or Acceleration. Could you supply a bit more info about your system and FSX version?
