Hi, I tried downloading your mod today however I had put both of the mods on the downloads list into my mods folder, then attempted to start up a game. But when I did immediately after starting the world it said "Shutting down internal server" and crashed minecraft along with my computer, any ideas?

Do you have the crash logs? There should still be logs somewhere even if it didn't show them on the crash.

I think this is them,
