On the demo I click multiplayer and poof! It goes with no error.

This is a commonly known problem, so I'm gonna have to pull a Qegola:

"USE THE SEARCH BUTTON!"

I searched for It crashes online and I got nothing :.

I searched for crash and within the first eight results... two of them were about this problem...

It was most likely this topic right?

Nope, it was another topic. Don't know if there was any useful information in it though...

So you flame a person about a search when you're not sure yourself? ouch.

If I were going to flame someone, do you think I'd be so kind and say "USE THE SEARCH BUTTON!"?

No, I'd probably say "USE THE ****ING SEARCH BUTTON YOU ****ING NOOBS!" or something along that lines...

But I know this question has been answered before, I have even answered it myself a few times.

Then instead of wasting this much time useless saying 'USE THE SEARCH BUTTON' you could answer the question in 30 seconds of your precious time.

Very well, the answer to the question is:

The servers were messed up for a while. They sent out something Toribash didn't like. Toribash crashed.

To fix this problem, you could, mostly likely doing the first of these:
A) Delete the offending server.
B) Not play Toribash.
C) Program the servers so they don't do it. (Please do... this is such an annoying bug)
D) Do A

Is that sufficient?
