Game Error for Battlefield Bad Company 2

I've recently downloaded Battlefield Bad Company 2 from the Xbox Live Market onto the Xbox 360 Pro and after installing it, I was able to play the campaign. But for some reason, when it comes to multiplayer online, it says Game error.

1. I turned started the Battlefield Bad Company 2 game

2. I go to Multiplayer

3. I pressed on quick match

4. I started the game

5. The game showed the coordinate map and of course the little menu that says "put me in a squad''

6. And while it continues to oad on the loading page the game says " game error: clean with a soft rag and restart the console" as if it were a really scratched up disc. EXCEPT IT ISN'T A DISC!

Its a game I've downloaded from the market. I've tried:

> Uninstalling and installing the game again.

> Uninstalling the BFBC2 Update and the Xbox Live Update.

> Clearing the Cache Fifty-million times.

> And took out any games from the disc tray.

Can someone help me on what to do, Xbox Live Support tried to help, but they tried their best.

:)

 

Reason for BF BC2 isn't working

On my hard drive I have the following files for BF:BC2:

Battlefield Bad Company 2 Title Update -14MB

Battlefield Bad Company 2 Update - 283MB

Battlefield Bad Company 2 Update #2 - 468MB

Battlefield Bad Company 2 Update #3 - 1.7GB

Battlefield Bad Company 2 Title Update #6 - 14MB

Battlefield Bad Company 2 LE Title Update #6 - 14MB

Dunno which ones are necessary but those are what I have.

 

Cannot install Bad Company 2 Ultimate Edition. Help.

I have Battlefield Bad Company 2 Ultimate Edition and when I try to install it for backwards compatibility I get the error "This game isn't playable here". Are not all copies of Bad Company 2 compatible? Any help would be appreciated. Thanks.
