when someone else is the host
I get the age of empires 2 expansion stopped working error, but when I am the host, I can enter the game and others can too. Can you help? This problem started happening today, it wasn't happening before. I attached the screen error

Hello, I think the solution to the problem is because of the mods used, I turned off all the mods and there is no problem. I think some mods are conflicting. For example, there were 2 small house mods or more than one small tree mod. I think the DE mods and the mods I downloaded from Voobly are blocking each other. Disabling the mods fixed the problem.

That would have been my next question.

Glad to hear you got it working, have fun on Voobly!
