could be a problem with the crack on multiplayer. Basically when the client (game) sends a packet to (talk) to the server, it parses the info to send only what is needed rather that an entire string of info that does not all relate to what the server wants to know.

Variables are used in almost everything to have global information.

Example.

lets say I set a variable called %gamedata%. this variable acts like a container (box/can whatever you wanna picture it as)

Now, lets say we dump our entire school year of work into this "container"

But we want to dig back up a piece of info on a section of one of the papers. Because the teacher wants to know what you had for "so and so"

Well, your not going to send the entire container of info as it would be useless to him since he only needs that one specific piece.

This is where parsing comes in. The "Packet" (term paper) is parsed and the info needed is taken out and sent into the packet variable and the rest is put back into the origional container. Then the packet is sent to the server and the server replies back with the same concept.

this is basically what that means, the problem you are having is your game (client) is not parsing it correctly or is parsing correctly but the data it was trying to find is wrong.

If the crack/fix is bad, or had some extra data taken out this can cause this sort of problem as the client cannot find the info so it returns an error. Sorta like "search/find"

You search but cannot find the info, so it becomes a problem or in gaming/applications "error"

As far as fixing it, if there is another fix for the game, you can try another one, if not you will need to use the origional exe and play with the cd when playing multiplayer.

hope that clears that up for you.
