Whenevr I join a server, it will always give me:

Impure client detected. Invalid .IWD files referenced!

C:\Users\thexxiao\Documents\MyGames\iw4m\main\raw.iwd

redownload the raw.iwd and replace it with the one you have.

redownload the raw.iwd and replace it with the one you have.

 

Aren't we supposed to update the raw.iwd provided by pigophone's post with the svn update files (The latest being revision 54).

nope, because the servers you tried to connecting to are still using r22. they check the md5-hash of your raw.iwd and if this hash is different from the server you get this error.

if there are servers running the latest revision you could play on them.

Oh that's why. Thank you for your help!

DONT USE IWD's AS SERVERS SUCK WITH SV_PURE
