Hey guys, I decided I wanted to get my new gamertag and some of my friends 10th Prestige on CoD4. I have been at this for about like 5 hrs now and cant seem to figure out the problem. I have tried about 7 patches, and everything works like the infects and camos, challenges, ect, but the xp does not stick. Like everytime it says "You are now 10th/11th Prestige and I back out nothing happens. I tried getting a kill in a public match still nothing. Anyone have any idea? Just to be clear I am infection myself using system link with my jtag and retail. I have tried several patches and the xp never works. They didnt patch it did they?
