Battlezone 1

I dont know if this is the correct place to post this, however, buddy of mine and I are HUGE fans of the mag arena map, problem is, I downloaded it off the Maps link on Battlezone1.net and it says to unzip all files to the addon folder, after i did that it says run the Mapadder.exe...well i cant because windows is saying it is incompatible regardless of the compatability options i choose. Anyone have any ideas on how i can get this map installed?

I checked the DM maps, and didn't find a "magarena.zip". Does the zip file for that map have a different name?

EDIT: Nevermind, silly me. It's there, it's just that the sorting order is case sensitive, so in the first "M" maps I saw it wasn't there. No worries.

Scared me there for a second lol now when i download that map zip, how do i install the map?
