[FIX] system.accessviolationexception: attempted to read or write protected memory

[A.Codewalker]

So I have seen a lot of posts scattered across the internet of people with this error and to my knowledge no work around (at least not one that worked for my situation). After literally weeks of searching the net, reading hundreds of log files and trying every so called fix I could find last night I finally caught a break and was rewarded for my persistence.

Without further delay...
This fix is actually very simple to apply and kinda mad at myself for not seeing it sooner, navigate to your SpaceEngineers.cfg file located "C:\Users\Admin\AppData\Roaming\SpaceEngineers" and change your graphics render (example at bottom of post) from Dx11 to Dx9, save the cfg file and run SE. This should allow you to launch the game, once inside you should be able to set it back to 11 via the in game menu (this will require you to restart the game) and with any luck you shouldn't see this error on launch anymore. After this fix i have run the game 3 or 4 times now and flawless launch every time. I hope this saves others some time as it took me forever to figure it out.

Gonna make my friend try this. He has some problems with DirectX 11 crashing the game.
And it keeps complaining on his drivers even through hes on a GTX 980 with the latest drivers.
