Hi all,is there a special way to unrar these 9 files? i downloaded the 9 files from megaupload and when i unrar the first one it doesn't unrar the rest( what i am missing? i am sure all need to be unrared to one building/map/poi folder i just can't figure out how ,if i unrar individually to the same folder the next will just replace the first(building/map/poi). any help is greatly appreciate it thanks!
