• Minecraft Version: 1.12
• BetterFps Version: 1.12
• Forge/LiteLoader Version (if any): forge 1.12
• Crash Logs (if any):
• Other Mods (if any): Optifine 1.12

When I click launch, it looks like it's gonna start up but then it just crashes! What do I do!?!?!

Which Forge and Optifine versions are you using? Can you send any crash logs?

I am using Optifine and Forge 1.12.

It looks like it couldn't load the config properly

How can I fix this?

So?? What's the problem.
