Regarding a crash on trainer activation. I am not able to reproduce this. The trainer activates fine on my end. If you have any issues and this is repeatable I would need to take a look on it via teamviewer to figure out why its crashing for you.
I just want to make sure that I am trying the same thing as you. Are you using the Trainer v1.4.8015 on the most recent version of Arizona Sunshine which is v1.4.8275 (oculus store)?
