Hi,
This is a frustrating problem. I have v3.4 installed and a couple of weeks ago P3D started CTD while loading terrain after starting a scenario. This would happen at about 25% during the load. Never happened before. The only thing that changed after my last successful flight was that I downloaded and installed some of the 55% off scenery ORBX had on sale. I tried all the old tricks of deleting cfg, shaders etc. Even deleted the new Orbx stuff. Nothing worked.
So, I decided to stop troubleshooting since v4 was being released. So yesterday, I installed v4 and I'm getting the same CTD. After booting up P3D v4 for the first time and loading the default scenario, it crashes at about 25% during the load. The dreaded g2d.dll error on both versions. I completely removed my nvidia driver using the DDU program. Loaded the latest nvidia driver.
Today, I launched v4 and was able to actually fly without crashing for awhile. I kept changing airport locations after a test flight. About the third flight, I moved to another airport and it CTD while loading terrain scenery. The three events are pasted below. I have no addon's in my v4. It's plain stock P3d. I would've said the issue was the Orbx install, but v4 has no idea Orbx is even on my PC. What is the commonality between v3.4, v4 and this g2d.dll error. I hope someone can help. I want to fly again! Thanks.

The AVSIM CTD Guide (see link in my signature) provides possible solutions based on my searches across the Internet at various FS sites.  The g2d.dll "solutions" worked for some. 

One of the other errors belongs to .net or Microsoft.net.  Dotnets are used to run applications in the manner the developer intended.  Make sure you have the proper dotnet installed.  I think their website indicates you must have a certain version installed.

The AVSIM CTD Guide also provides a technique to investigating your crashes.  Page 10 has a procedure that fixes most CTD's and Freezes.  In your case, I would disable the scenery you installed from Orbx one at a time until the problem goes away.  This way you can narrow down the offending scenery.  Most of their scenery requires objectflow and that is loaded at startup via the dll.xml.  If it is corrupted or an old version, then it could cause the crashes. 

None of the scenery from FTX/Orbx that uses objectflow will work in P3DV4 until they make objectflow compatible.

Hope this helps.

Best regards,

Jim
