I made my last flight maybe two weeks ago and today after some night shifts I thought flying again to relax and fly thorugh the fog as we have in real life too.

But P3D is starting, you see for around 1min the P3D screen. Then EZCA v2 comes in and in Win10 taskbar the micro icon appears. Suddenly the P3D screen disappears and thats all. Even after 30min nothing happens. In taskmanager it says it's still running using around 25-32% CPU and 666,2MB RAM.GPU is used with 1-3%. Except RAM all values are varying a bit.

I did not install something new as I wanted to fly the leg back I flew two weeks ago.

Any errors in the Windows Event Viewer reported?

Not so far I can see. I'm also wondering while its in the task manager still displayed as running and active and also CPU and GPU values are changing. For me that would indicate it still works. But before that day I always had the P3D screen. Sometimes it took 10-15 to load whole P3D, okay. But now it disappears and is only able to exit via the taskmanager.

I also tried reboot of my PC and deleting the shader chache and a clean and new P3D.cfg. I'm also running it as Admin just for info.

I found that it seems the problem is inside %PROGRAMDATA%\Lockheed Martin\Prepar3D v4 . After removing this folder (as suggested in P3D guide) it worked.

It seems it is the dll.xml file causing the not starting. I tested and deleted only that file at the end and then it worked.
But inside there are only 4 entries by PMDG, RAAS, PMDG HUD. I checked the files linked to the entry and they all exist.

Deleting RAAS PRO entry solved the problem. Don't know why, maybe its I have not an Aerosoft airbus installed nor I own the full RAAS version. Maybe its a leftover from my previous Aerosoft airbus version and as I do not fly the A330 at the moment I removed them. Let's see if I can do a flight tomorrow
