(adsbygoogle = window.adsbygoogle || []).push({}); I did the cheat to et "Five" then I came back to Veteran campaign. I was at the begging of the first vietnam one were u have to get down the hill. I kept playin missions but didnt get any trophys? Whats up?

Well you cheated, so you won't gain trophies. This way you could do the hardest missions first and it's not what Treyarch wanted. My advice is to wipe your save data and start over.

does that make you lose your online rank ??

You've been playing since CoD4 and you don't know? Your info is stored on activisions servers lol. It's perfectly safe.
