Ahh, as I expected. You have Windows XP, and I Windows 7. Windows 7 only allows one form of zip.Will post screenshots if I get back to my computer soon... on an iPod.
I think the problem is that he has WinRAR. I only used WinRAR for like a week, then I got Winzip.
SO HOW THE HELL DO YOU GET MAPS?!?!?!?!
