Experimental problems: Need Answers!

I load a level in the experimental branch, and when the level opens, the game crashes. It said something like "failed to open shader, fatal error."

However, in the stable version, I can load a level without any trouble.


Any advice would be nice

I really want to try the beta so I can drive the Hirochi Sunburst.

I tried it on one computer with many mods, then on a computer with no mods. Neither of those worked.

 

No, I haven't.

I tried, but it didn't work.
