How to import an animation made in blender?

So I’ve been struggling with this. I just had some one create me an animation for my game, and he created it in blender. Only problem, we don’t know how to export it into Roblox as an animation.

I tried using that blender exporter plugin, but every time I’d paste the link into the script my Studio would crash. every time.

Not sure what to do really.

Any help appreciated, thanks.
