Approved it's working

Bump the Thread
Well, if more confirm this works, it may be sticked. Else not.

ty vm going to try this now if it works thanks will follow

ok this works ok if you dont want to use the DLC you downloaded and paid for!

well, it worked for me and my friend, but only this way: i had to join a lobby and he had to follow after i told him there is a place to join :S

It works. You can play with non DLC people if you do the above steps. If you want to play DLC again. Exit the game and then put the files back and bam, you're good to go!

yes,it's works.if u want to play with friends.that havenot bought the dlc yet.when u want to play on the dlc map,u had to add files to the 'main'directory

can i just move these file to an other folder i made "dlc files"??

omg it says main iw25 is different from the server

removed by originator

For some reason i dont have iw_26 and iw_25

may be u havenot dlc?

Oh yeah, IW fixed this with one of the latest patches btw.
