Title explains it all. I have no idea what this means or what to do to fix it. Here's the crash report:

That is the only version available to be downloaded. I am trying to get the forge version.

Can you try downloading it once again? It should be giving the proper version now.

It only says "source code" on them. Are any of them correct?

Hmm, I'm not sure where you're looking at if they all say source code. There should be a non-source version available. Here's various links to the current Forge version:

Ah, I was clocking on the download link at the bottom of the page instead of the one at the top. it does not say source code anymore.

You appear to have downloaded the -sources-dev jar, which isn't usable by players. Check the downloads again for the jar without -sources-dev in the name.
