Ok... this is how u get the maps to work.. Download the map and unzip it.. once u get it unzipped and it shows something like "map.mpr".. u open ur tib sun directory..click and open ur sun directory and then click on the "map.mpr" file and hold and drag it down over to ur sun directory until it shows up in ur sun directory...then just open up tiberian sun and it will be on ur map list...it sounds complicated but it really isnt..do what i say and ull be playing the map in minutes
