DMZ Tutorial Help

Can anyone advice me on what to do? when i first entered DMZ mode, for some reason, i could not enter the target area in the tutorial. i tried multiple times. afterward, i quit. a while later, i tried again, and it now shows my weapon durability is at 0%. however, im not able to fix it to enter codm at all, because the tutorial is forced on me. i have to press start match and finish tutorial to fix my weapon, but i cant start a match without fixing my weapon
