Update, I tried to reinstall all of P3D as well as re-download and install the 737 and having the same issue. There is no longer a message telling me it is initializing and to wait 15 seconds like v2. No control surfaces work and no gauges, screens or switches work. Any ideas?
It won't let me copy a file either, but here is the error log. Looks to be a problem with the dll's somehow:
[error.0]

All the way down to error.176 but they are all guage errors not loading from here.
