Running the editor and game concurrently crashes both?

[mastersmith98]

When I started working with Amnesia I was able to run the editor and the game side by side, this made testing out maps a lot less painless. But now for some reason when I start either the game or the editor first, then start the game or the editor after it, the one started afterwards crashes. I haven't made any changes to my computer or anything significant since this problem started happening so I'm not entirely sure why this is happening.

At first they crash with the "Renderer #0 could not be initialized" error and then black box comes up with a crash log.

I've also made sure to close down all background programs baring steam, since amnesia has to launch from it.

Does anyone know of a possible fix for this?
