has anyone gotten multiplayer to work yet?

I moved your post to a new thread, because it has nothing to do with the Bonus Content Unlock Codes. That's why your other post was removed.

Whats wrong with your multiplayer?

LAN Problem STALKER
 

i startet a lan game with hamachi....my friend had a problem-your cdkey is in use(or so)- but he did not enter a cdkey when he installed the game...so my question...what value in regedit HKEY_LOCAL_MACHINE\SOFTWARE\GSC Game World\STALKER-SHOC ...InstallCDKEY is normal?...my is "vv" and i did not enter a key when i installed the game....my question what is your value when you forgo:) t to enter the cdkey? thx bass-t88(german guy)

Well you would have a cd-key from your original! as would he.

I'm sure you can change the CD-key any time somewhere in the game... (And, as for CD-keys, read forum rules #1 and #2.)

In the MP beta when you were in the serverbrowser there was a field to enter the cd-key. No idea if this has changed or not in the full version (beta never asked for key during install only in-game MP menu).
