Killzone codes not showing up

Maybe someone can help me...
I got a bunch of codes for Killzone Liberation, copied them to my .txt document, and named it UCUS-98646 like its supposed to be. I activated nitepr in-game and there were no codes. I thought maybe it was because I was using mkultra v7 so i switched to revk stable and I get the same problem. I checked the ULUS# by looking at my savedata file for KZL and its the right one. I even re-named the .txt to make sure there were no spaces or anything in the name of it, but I still cant get my codes to show. Any ideas?

same thing here

first make sure u have # in front of each code and a space between each new code. does this happen with other games?

Make sure you have the right UMB code on your .TXT doc that you put your codes on.

perhaps you have an european or jap vesion of killzone

no its usa and ill try the "#"
