Well, unfortunatly, I don't know exactly what went wrong. I'm pretty sure, however, that the problem stemmed from the fact that I (very, extremly stupidly) did not back up the modeldb file.

I was following Musashi's tutorial about as closely as I could, just going to the Cossak Musketeers every time Musashi said Reiters. I got to the modeldb file and copied the Cossak Musketeer part out of there into another file so I could play around with it. It was at about this point that I realized the tutorial did not cover what I was trying to do.

The tutorial, as far I could tell, just took the Reiters, painted them purple and gave them to the Byzantines with a bit of stat modification in there. What I wanted to do was take the Cossak Musketeers, put them in Nobel Highland Archer costumes and make an axe their secondary weapon instead of the sword. I think in order to finish what I wanted to do I had to basically make a new skin. So I figured at this point I was in over my head, and just gave up.

But that's neither here nor there. The point is, I think when I copied the Cossak Musketeer stuff out that modeldb mess I screwed something up, either adding a space or a letter or deleting something, I don't know. If I had known I put or removed something from that file that I wasn't supposed to, I probably wouldn't have been able to fix it anyway, cause I wouldn't have been able to find the mistake.

I guess that's a rather costly lesson to back up your files. I suppose I'll just have to keep reading the boards until someone else to make a gun-totin' scot.
