So, I recently start to play my copy of MW2 for PC using Steam.

But every time I try to play Multiplayer I load the map up then and I'm sent back to the lobby with the error Files different from the server.

Can someone please help me? What could be causing this error and how could I fix it?

What are your system configurations ? did you tried update your copy to the current version on Steam? –  Michel Dec 24 '12 at 7:01

1 Answer 1

First, let me just say that sometimes it could be the server that is different from the client, but if this keeps happening there are a few things you could try:

  • In Steam, select the game, then Right Click->Properties, go to the Local Files tab, and click Verify Integrity of Game Cache. If steam finds any outdated/missing files, it will inform you and start downloading them.
  • Browse to the steamapps folder, locate your copy of MW2, and inside /main, delete (or cut out) all the iw_XX.iwd files. re-run the verify integrity. It should pick up the missing files and re-download them.

Finally, the most drastic:

  • Right Click->Properties, go to Local Files, and Delete Local Game Content. Once it is done, go into steamapps and make sure there are no remaining files. If there are (shouldn't be), delete them. Then re-download the game.

I got stuck with the last option on MW3, it sucked, but luckily I had the game discs (I bought it retail). I just installed off them and then let steam run updates.
