I'm having a problem where I open toribash and then when I go into multiplayer it the game crashes. No idea why it does this, what should I do?

same here

Go and download either the steam version or the latest (4.8+) version of toribash, there have been too many threads of this same problem.

^ the above explains it best.

Also if you are having a problem with the game, you can always look at other threads where the same problem is most likely solved, or the stickied threads for help.

alright so i made got it on my steam account, logged in with this account and it all ran smoothly.

Just one thing, can i get my toribash achievements on to my steam toribash achievements?

They automatically transfer over both ways so it doesn't matter what you play on, you'll still get all the achievements
