Resource file version does not match with host error

I recently started playing AVA again and decided to play some co-op. I created a game, waited for some people to join, and pressed start. Once it finished counting down and let me into the game to load, the screen turned black with the AVA symbol in the middle of the screen and kicked me out prompting me with, "Resource file version does not match with host. Exiting room. Please exit the game and restart. Patch will start automatically."
I then created another co-op game after getting this message, BG:BeginZ[Easy], and got the same message after loading and getting kicked.
I've already reinstalled the game twice and still get this error. Help would be appreciated
