Error: include file ca\missions_e\loadingscreen.ext not found

[Deathcon5 10]

For some reason I can no longer host multiplayer games. I can join them, and I can play singleplayer. When I try to start a multiplayer server I now get the pop up:

"include file ca\missions_e\loadingscreen.ext not found"

as the game shuts down.

I ran the Steam verify local game cache. i tried uninstalling the game and reinstalling. I found and unzipped the "ca\missions_e" folder and found the "missing" file sitting right there in the pbo! So why am I getting the error all of the sudden?

here is the info from the rpt file:

Found the problem!

The error was popping up when the game would try to pull up the list where you choose which mission you want to play. Well, at least that is the screen that was supposed to load when the error popped up instead. So, I deleted the last mission I had messed with in there and poof no more error and crash. If anyone else has the problem, the folder (for steam users) is:

C:\Program Files\Steam\steamapps\common\arma 2 operation arrowhead\MPMissions
