Modern Warfare 2 crashes when host goes to second map

Some extra attention for the nr. one of all MW2 MP Errors in these last couple of days.

And again a fix from the PC community. Not a word about this error from Infinity Ward, Steam or Valve.

42. Modern Warfare 2 crashes, when I am host, on the second map.

Seems the "second map host crash" comes from STEAM. (!)

You have to download the Steam BETA Client.

You can do this in the Steam Account Settings.


Steam settings >> Account >> Beta Participation >> Change it to ON

and restart Steam.


This fixes the crashing if you are the host. The current MW2 Disconnects and Time outs are both result of same error. Because most hosting players don't know about the above fix (yet).
