CL_C Command error

It always starts when I shoot someone.
Comes up:
"Error
CL_CGameNeedsServerCommand: Areliable command was cycled out."

It keeps on popping up and kicking me out of the game. If I get out of the game and go back in it works sometimes. Is there anything you can do to get rid of this?

It does seem to come up when I have upgraded my Prestige. But after a a couple restarts im ok again.

ive cracked it what i descovered was that punkbusters server codes wasnt matching the same server codes as the ones used on call of duty 5 so ive updated them to match and now i can play online again with out getting kicked as soon as i shot some one

heres the reason and the solution...
Ok so I was trying to quick level up in prestiege cause I had a blue screen dump without a backup file made,so I went to the quick level up servers so I could get it done fast,but I kept getting a cod error.The error read

"CL_CGame needs server command:a reliable command was cycled out"

so I went to google and searched the commant out and found out that if you try to level up in prestiege mode in a server that levels up at a point rate of more than 3000 points a kill,it will come up with this error.you need to level up in a low point server till you get to about 10,000 points then you can go to a high point level up server after the enitial point minimum.

hope this helps you out

that happens to me, but now i know the problem...
for me cod 4 is 1 million times better you dont have this error there, the graphics are better.
I bought the game and i feel like some one had fool me because there is so many bugs and errors... last week i was at last prestige mode and this *bleep*ing game snd to me a error menssage and then my level had back to 0...

COd 5 sucks sorry but it is the true
