Ok I downloaded the mappack. I opened it up and did all the instructions but when it came time to patch the maps it didnt work.

It didnt make new maps in the modified maps folder!!!NOTHINGS THERE.

I put all the .maps in the orginal maps folder and put the shared.map in the modified folder but nothing happened. NOTHING WAS TRANSFERED TO THE MODIFIED MAPS FOLDER.
