CoD:UO invalid .pk3 files referenced

[Medic]

Anyone know wtf this is? It's saying specifically

C:\Program Files\Call of Duty Game of the Year Edition\uo\ZZZ-AO_MOD_V2.pk3

Is this the result of one of a thousand million fucking mods? (all of which invariably make the M1 reloadable mid-clip, jack up ammo counts or rates of fires, and add laser sights among other shit)

It's giving me this on a lot of games. It'll let me load the map but right up until the point where I'm in the game it aborts and gives me this screen.

I'll probably un/re -install and disable downloading but if there's another solution, I'm all ears.

This is indeed the result of CoD auto-downloading all kind of mods when you first try to connect to a new server. Have you tried just deleting the file in question?
