Limitless Pixelmon

So, I'm not sure if everyone is using the Pixelmon launcher, but when I select "Beta 6", It says there are no forge versions to use. I don't know if I can just download Beta 6 somewhere, but I'm completely stumped.

I'm actually getting this too. There's no way I can log onto the server as well, and I'm not sure if it's because of this or not.
