Crossfire Client Error 1_3 (i'm not glitching)

Supposibly I heard when you try n glitch you get the error 1_3. But I mostly get this error at the Sewers and I am very big on uses melee weapons. Almost everytime I fall in the hole i get that error and I seem to be always doing well and its upsetting. Is there anyway to help it

^^^
Just like they sayd, or if you keep getting this, save
all the stuff u need like screenshots, then just delete crossfire,
and re-download it! it might help to reduce errors
(If you get many times errors, so you're getting quick errors, or anything
i re-downloaded it either)
If you re-download, the errors are away, till you glitch or something..
if you get one errors.. its gonna show up more... soo yeah

Hope i helped u!
