Did that- same error. That was the same installer I had to begin with.
Actually, had a closer look, and I erred by saying bad files- actually, they're missing, listed as follows:
NW10patrol
NW10patrolenemy (I have NW10patrolallied instead)
NW14rescue
NW17patrol
nw17patrolallied
NW17patrolenemy
NW22diplomat
Now what...?
