N44 upgrade and Volcanoman art problem

[Sergeant Bush]

I have been out of wargaming for quite awhile but due to some recent changes and further study got interested in playing N44 again. I am now on Windows 8. I re-installed the game, downloaded the N44_113 patch and installed it. When I check the "about" game under the help tab, it still shows the version of the game as N44 1.0, 2000. In the past I thought this updated with the patch. Then I tried to install the Volcano man art I so enjoyed when I was playing previously and a few files unzipped OK but then I got this message:
"Cannot overwrite C:\HPS Simulations\Normandy'44\American' - you do not have the correct permissions"

Any help with these items would be appreciated.

The biggest issue to me is that when I try to play in 3D zoom in mode the graphics are "toy soldiers" rather than Nato symbols. I find this difficult and would love to use the Nato symbols and use Volcanoman's art.

Thanks,
