Hi, I just discovered this whole map editing thing and am trying to get a few that I downloaded to work in WoW Map Viewer. The two files I downloaded were named patch-m.mpq and patch-5.mpq. I renamed patch-m.mpq to patch.mpq and copied it into my Data folder, replacing the original mpq file. I got it to work in WoW map viewer, but lost a lot of other stuff. However, when I did the same thing with patch-5.mpq, wow map viewer crashes.
Am I doing this right? Thanks all.
