How to update BFME II maps to work with Angmar faction in ROTWK?

[DudeBoyz]

I have a few third party maps that I downloaded and they were set to work with Battle for Middle Earth II.

I have bought the Rise of the Witch King (ROTWK) expansion and am finding that if any of the computer AI opponents (like when I play skirmish offline) end up being the new faction (Angmar) then the only thing that happens with that faction is they have a stronghold and two builders, but they don't do anything. They just sit there and nothing happens. They don't build things, generate troops, etc. like all the other factions do.

Is there any way to get these maps updated so that they work natively with the ROTWK expansion?

I tried opening the map in World Builder and just saving it to the same file but that didn't seem to do anything to fix the problem.

I'm very unfamiliar with how World Builder works, by the way.

So, I'm asking if anyone might be able to help me out here. How do you go about getting maps designed for BFME II to take full advantage of the new faction in ROTWK?

Thanks much.
