I bought a used copy of JA the other day. After I beat the single player part I decided to go ahead a play multiplayer. I updated and played on a server for about 10-15 mins then it just froze and shut off. At first i thought it was just a server problem but then i started my own and it did the same thing. I cant remember what the messege said but, it is annoying. The game runs smooth so i guess my vid card and ram are not an issue but i dont know.
can someone help me with this problem.

try it again and write down the exact message you get, if its in a little console box when it crashes, try copying and pasting the whole thing. a crash coudl result from a lot of things, its hard to guess which one you are suffering from ;)

CL_ParsePacketEntities

it keeps saying that

but im accually able to get in the servers though for a good 15 mins or less then freezes and goes back to the menu
