I've got a big problem!
I've Vista and I've Medieval 2 and Kingdoms installed.
I've also installed third age 1 and all was perfect.
I've downloaded the v.2 and the patch 2.1, but when I've installed the part 1 of v2, the installation programme say to me that there is an error with a file data\unit_\models\units\textures\elvish_off_norm texture (error 21FC) when the installation's progress is at 91%
When i start a new campaign the game crush on the loading screen (the game exit atomatically and the pc given't me any message)
I can play the historics battles and the costums battles, but Iwant to do a campaign!
I've tried to re-download all the files and to install them when the UAC is disabled, but nothing changed!
So I've installed the v2.1 and I've tried to modific a file as indicated in the forum, but nothing changed.
Can someone helps me?

Thanks to all.

P.S. I'm not English so I can't write it very well, I'm sorry.
P.P.S. I don't understand lots of informatics word.
