EDIT: Looked through the topic and they said It happens when lucasarts bans your game for spamming/other stuff in multiplayer.....read the topic at the top for more info.....have you been doing anything illegal/annoying/spamming?

it also happens when you use a key from a keygen, only the key that come with a original game work online

EDIT
hay i have a nother problem some times wne i try to join a server it loads all the red things bt nothing happens it just changes the tips and tricks

I really don't want to play a mini-moderator, but I'll say this:
1. Use the space bar and normal buttons in the correct order.
2. Use the punctuation like we asked you to.
3. It's also a rule to not double-post, you can edit your old post.
Seriously, man. I first of all don't get motivated to help you if you ignore all our directions and secondly; if you keep ignoring moderators you will get yourself banned. (I say this as a warning to you; elitetrooper. We totally cannot help you if you continue this and get banned. I'd really want to help you, but you're posts are simply not making a lot of sense and I've got other, more usefull, languages to decode if I want to)

ok im so srry i relly bad at spelling and grammer.i get Fs ok but i relly need help so im not ingnoring you moderators im jsut to fast at typing but bad at spelling so can yuo jsut help me with my question

The reality is that if your CD key doesn't work you have pirated the game. If you own the discs, contact Lucasarts support to get a new CD key. We can't fix that problem.

Oh, and typing with proper grammar is a common courtesy. If you can't do that then you make things nearly impossible for us to read, and nobody wants to help. At LEAST use punctuation if you want help. Period.

Long story short we can't help you with this problem. You either have a pirated game, or you need to contact Lucasarts with your proof of purchase to get a replacement CD Key, because someone took yours.
