Well this weekly challenge is "Like A Record, Baby" and this you CAN reset but remember you CAN get banned for resetting. Just when you see the 3000 cR pop up or the challenge completed pop-up, disconnect your ethernet cable and then reconnect to xbl. I DID NOT DO THIS BECAUSE IM LT. COLONEL GRADE 3 ALREADY BUT MY FRIEND DID IT IN FRONT OF ME SO IT DOES WORK. I believe this is the first weekly challenge you CAN reset... Im not saying to do this only if you want. Please don't flame
