Minecraft Camera Studio Mod error?

I have a problem with the Camera Studio Mod or For Minecraft.

Undzwar I have installed Forge + Mod and it works until then when I have marked the points and want to play.

Then the game aborts and the error message "It looks like you're using an unsupported, modified version of the game."

However, I do not understand the problem because my PC should actually pack the mod.

My Pc Details:

Intel Core i5 6400

GTX 1050ti

8GB Ram

Does someone have a problem solution?

Have the mod already uninstalled and installed but nothing helps.

Need the cinematic recordings very urgent, because I want to cut a cool video.

I thank everyone who can help me.

Kind regards

Did you start the unmodified version before installing Forge?

What does "Show more details" mean?

The "It looks like you're using an unsupported, modified version of the game." you can ignore completely. This is not a mistake

Poster times the errorlock

If necessary, you can even fly around with f1 as a camera with cmdBlocks

It is sometimes so that a mod does not work…
