MFD, PFD, both dark on Battery power. APU won't start

[Gobysky]

I've updated both X-Plane 12 and CL650 to the latest available. 

Now when I turn the battery on,  the glass cockpit (MFD & PFD) does not come on. The APU won't start either. 

Also, when I use the camera by right clicking the mouse and move around, the image stops, stutters, then finally moves on. A myriad of issues with these updates. Don't know where to start. I've uninstalled, and reinstalled both X-plane and Cl650 twice now. No change. 

How do I find the log files that folks ask for? The one log file I saw is huge text file. Is that the one?

Probably. It’s called Log.txt.
