I feel silly asking for help about a simple task, but....I need help installing this mod. This is what I did:
1) downloadloaded & saved it to Civ4/BtS/Mods
2) the file is: 'romrevolutiondcm2_1.rar' (now sitting in the Mod folder)
My question is, how do I extract it? It doesn't even give me an option to unzip/extract it. When I try to 'Open' it, it says 'Windows unable to open this file'. Do I need another program to do it? (I have Windows XP).:cry:

(PS - I deleted Python from BtS/Mods/RoM2/assets; may need it back if I cant' get this to work?)

Do you have an unraring program installed?

I'd recommend 7-zip (http://www.7-zip.org/), it can unzip rars and anything else you throw at it and is very useful.
