I've kept the same username for that forum to make life easier, hope this helps
I had over 80 crashes during my 3 time playthrough. First two times I was stuck at the same place you mentioned due to using the trainer. DO NOT USE THE TRAINER before you meet Talia. After you go thorugh the basic gliding part, when it comes to battle, DURING THE BATTLE you may activate the trainer, BUT NOT BEFORE THAT. It will cause the glitch to appear again.
This is the way I played on my 3rd walkthrough. But I got stuck AGAIN before the last boss battle.
