Challenges aren't completing, please help.

[CrumblyHumble]

I recently bought the game because I loved playing the multiplayer on the PS3 when I had it, I leveled up to rank 24 then I got put into a hacked lobby and my stats went to the max and it unlocked everything to unlock, guns, attachments, camo, titles, and emblems etc.

So I did a stat reset and the other fixes if you enter a hacked lobby, but now it seems that any of the challenges won't complete, it won't show that I've gotten kills for the guns or the perks. So now I'm stuck because of some idiots who can't play the game properly, please may anyone help?

If you reset your rank then challenges should have unlocked...

I'm back to rank 8, so I've just unlocked a few challenges, but my point is that even with the gun challenges to unlock attachments, the kills I get won't register for that weapon, like getting 10 kills to unlock the noob tube.

Doesn't it take 10 kills to do that anyway? Or do you mean you have 10 kills and can;t get the tube?

In one game, I got 19 kills using the first assault rifle, so I should have completed marksman 1 challenge but it didn't pop up.

I'm having the same problem. I just bought the game and none of my kills are registering for any of the guns/achievements

just followed the steps on here and it fixed the problem. I also made my mpconfig file read only
