2 questions/ideas: did you install the gold patch for 1.5? even if it says you have it reinstall the gold one for your area (us, uk, europe etc etc) use europe if you not listed on any of those listed. Cause if the mod was made for 1.5/kingdoms and kingdoms isn't working right the mod won't either

.
and 2) i think all you really need is kingdoms.exe files. So if you need to install mtw2 from your disk on another system on in the virtual things above, and just steal the kingdoms.exe out of it, and put that in your install manually, should allow you to run kingdoms mods.
does kingdoms campaigns run correctly?
