Go into the A2WarMod addons folder and remove the file that says WarMod_loading.pbo
If you remove WarMod Loading screen then you get the default loading screen for Arma2.
Are you having a problem with the loading screen in terms of the bug that was reported eariler like your unable to load save games,
or you just dont want the loading screen?
How does the loading screen look for you, as on my end I have a 1900x600 res and the pic is stretched, i tried alot of things and
no matter what I cant get it to look good or work right like in Arma2CO.
