I didn't make it!
You've probably guessed, but I've been getting "CL_ParsePacketEntites" problems almost everytime I attempt to connect to a server or create my own game. If you have any suggestions or solutions, please post. It will be greatly appreciated.
Sounds like you have a no-cd patch ;) No way around it, there is no workable patch so you have to reinstall JK2 to get the game working again (with the CD).
