Oh, I'am not alone with this!
Problem is the same as at CATMANEXE and Petrovski.
MAX gives out the same report at the start.
I have 3dsMAX7.0 + SP1 and Civ4_plugins, but have not Civilization 4.
And try modeling in the Oblivion.
Reinstallation of Oblivion gives nothing!
Here the file CivilizationIVMaxPlugin.dlu, opened by Wordpad:

I have not folder "maxsdk" in 3dsMAX directory.
May be that's answer, why plugins not run?
