My issue is that it takes over 10 minutes for P3D to start or sometimes it won't start at all and will crash with an api.dll error. Where as if I do not have MAIW Matrix packages installed it will take an average of 2 minutes max and I will not experience any errors.

The installation directory is ...

I have tried and failed at downloading regions with MAIW Matrix and adding the scenery into P3D manually then removing the regions (as they cause loading issues for me). Where can I find the scenery files for Air Force Bases such as KDOV and KADW etc for P34?

Thank you
