Ok, I am trying to prestige in MW3. I am now prestige 10, level 80. I click Prestige Mode, then go past the first two prompts. However, on the 'Enter Prestige' screen, when I click it, it just closes the 'Enter Prestige' window and goes back to the barracks. My level is still the same. I can see the next prestige icon at the end of my xp bar. How do I fix this?
