i downloaded all of the dlc1-4 and put the main stuff in the main folder and put the zone stuff in the zone folder when i go play a map witch i just installed i get a checkered loading screen and i have to alt f4 to get out of it is there some type of software i need to get in order to install the maps? i looked around on the forum for installing these and didnt see anything :/

Are you sure you copied the DLC/main/ folder contents into IW5M/main/?

.iwd files goes in main folder

.ff files goes in zone/dlc folder

Yeah i copyed and pasted it in the right places i just cant figure out why it doesnt work I deleted the cache too so it should be reading it and after playing for the last hour or 2 ive realised i can only play on dome... But i have all the maps installed thats why im confused and looking for help

Can you take a screenshot of your zone/english and your zone/dlc ?
