Im trying to play mercenaries 2 world in flames for ps2 but it frezes before i can play it how can i get it to work

If its just this game that is doing it, then the disc may be dirty or scratched. Try cleaning it with a dry duster (wiping the disc from centre to edge). It that doesn't work, then have a good look at the disc for any scratches. If you do find any, then the disc is probably broken.

It crashes because of EA :) They have problem with their servers and I think they've been shut down servers for a while. That's why you can't play online. But when I play offline, I can't save the game in any point or otherwise it says "Save failed" for plenty of times. I don't know why :)

better go on a pc and contact xbox and or EA themselves find out at the source, cause the problem is obviously there

The game itself is just defected. You might be able to find your answer in this thread

have you tryed conneting to ea.com???

it could be your disc

Problem seems to be the XBOX Hard Disk Drive (HDD). Run the game and play it once for about 30 mintues, then try again with the HDD inserted. It should now work.

The problem seems to be a conflict with the HDD or with the EA servers, as the XBOX Live account will try to connect to the now dead EA servers for this 2008 title.

If all else fails, you will need a portable memory card, not the HDD to play this game. It's okay if this is the case. Create an offline profile. The game no longer connects to the EA servers anyhow.

Download the demo of army of two accept ea's terms and conditions start game quit put mercs 2 back in and it should have sorted it but if not you need to borrow rent or buy the full game to get your problem fixed. This is the same problem as the freezing on the main menu.

Get the latest patchs of xbox live.. if not try the game on a diffrent xbox

its either a driver or a game update needed do you have vista or xp if you have vista that's the problem
