I just recently purchused Crysis Maximum Edition from EB Games

It came with the 4 cd's/DVD's and 2 Cd-Keys One for Crysis Warhead and one for Crysis

I've installed Warhead and Wars and the CD-key worked with Warhead, but when I go to play online with Wars it says my CD-Key is invalid. I've tried both the Crysis and the Warhead CD-key and the same story. Apparently the Warhead one should work.

By the looks of it I'm not the only one to have had this problem with Maximum Edition.

Anyone know how to fix this problem, thanks!

Almost same here.

Cant start warhead, but can start wars. Very anoying with DRM...

Bought the game from webbhallen.com (a swedish store in sthlm) if it helps.

i have the sane problem, i just purchased crysis maximum edition from game stores.. and i have installed crysis, warhead and wars but wars wont accept the cd key and let me play online... i can play on servers which dont have punkbuster enabled but not ones with it.. and i would rather play on ones with it so its not full of cheats.

i followed lots of ways to fix this problem but it still does not work.. and you are supposed to use the warhead product key to play it as it is a warhead add on type of thing.. the 2 other crysis games work fine but wars is just being stupid.. i did use to play it before but lost my game disc which is why i got the new one and created a new account with the game.... so if anyone knows of a way to sort this out please let us know as it is very anouying to pay my well earnt money for a game that does not work.,, also i have emailed crytek so if i hear anything back i will let you all know

Thank you, Black-OPS-LoneWolf.

This is DRM done wrong, iam going to download warhead from TPB now, since nothing is happening here...
