Jedi Knight 2 Errors Maybe JK3 Also?

When I play Jedi Knight 2 on-line, or on a lan, I get the following error:

cl_parsepacketentities

And then it goes to the main menu. This is a retail version of the game and have not used an no-cd crack of any sort. I've updated my nic card drivers. So I have no idea what it is. Any thoughts would be very helpful. Thanks.

You only get that error if you use a no-cd.

Did you patch it completely?

I didn't patch it or anything. Fresh install. Game requires the cd to play.

I get that error also. If if you are talking about Jedi Academy then I think your going to have to wait untill it officialy is released and patch's are avalable for it.
