@THE_R0ADKILL Crysis Wars is the MP component for Warhead and the servers were shutdown years ago. So even if you wold not receive that check message, you still would not be able to play it, as the MP servers are shutdown.
Sadly, EA isn't the single owner of the IP and with Crytek being almost bankrupt, EA can't do anything, as Crytek is the graphic engine's owner and the game developer. So unless Crytek does something to remediate the game's problems on the modern OS (which is very unlikely, in its current state), the MP side is dommed (and probably the game, too, as they never removed the SecuROM online copy protection, a protection that seems to be phased out by MS, lately, just like the old copy protections : SafeDisc, SecuROM 1 - 5, StarForce or TAGES). As SecuROM online servers seem to die down, affecting the titles that did not had the copy protection replaced or removed, the fate of the games that used SecuROM online protection is becoming uncertain. Some companies will probably do something about it, if they are the IP owners, but others will probably remove the games from sales and send them to the games graveyard.
I do not work for EA and i am not associated with the company in any way. I am a player just like you, trying to help wherever i can.I will not answer to any unsolicited PM.
