JLK815

I HAVENT PLAYED 911 FIRST RESPONDERS IN ABOUT 2 YEARS. RECENTLY PURCHASED IT AGAIN FROM ATARI ONLINE. DOWNLOADED IT, ALSO DOWNLOADED THE LOS ANGELES AND NEW YORK MODS WHICH ALL WORKED WHEN I PREVIOUSLY HAD IT ON THE SAME COMPUTER. THE GAME ITSELF WORKS, BUT I CANT GET ANYTHING DONE WITH THE MODS, IVE EXTRACTED, PUT THEM IN DIFFERENT FOLDERS, RAN THE SET UP FOR THE LODS ANGELES MOD. BASICALLY HAVE DONE ALL I KNOW TO DO BUT CANT GET THEM TO WORK. CAN ANYONE GIVE ME A STEP BY STEP PROCESS ON THIS OR ATLEAST POINT ME IN THE RIGHT DIRECTION
