Anyone know a quick fix for the Halo 2 error?

My friend and I are trying to play the Halo 2 campaign co-op but every time we try launching the first mission it disconnects at the load screen. Is there a quick fix or is this an error that they are still working on?

Try setting the visuals and music setting to classic. Then once in the game you can change them. That is what’s works for me.
