When I open internet game, I see GameSpy login screen
First of all, check whether you are running correct game version, you can do so by looking into bottom right corner, there should be some number like 1.1.5767 or 1.1.6115 or 1.1.6156.
The required version to use CryMP client is either 6156.
If your game version is 6156 and you still see GameSpy log-in screen, make sure you are launching the game using shortcut generated on the Desktop by installer.
If you don't have any shortcuts on your Desktop, just run installer once again or launch the game with -mod sfwcl argument
I have AMD CPU and my game is crashing
Make sure you are launching game.exe installed by installer and not Crysis.exe or Crysis64.exe when running the game.
Do I need to register here and How to create an account?
No, you do not need to register in order to play. If you don't register, you will simply be assigned your static profile ID based on your machine hardware ID.
By registering you will gain your own profile ID, so even if you change computer, your stats will still be collected to this account
I can't see my server on the website!
First of all, make sure you are using some SSM, either SafeWriting or CryFire or even if you don't use any, make sure you modify your CryNetwork.dll and replace all occurences of "gamespy.com" with "m.crymp.net"
If now, you don't see your server on website, but can see it inside in-game server list, that means your server is not accessible from public internet. This can be due to your ISP simply blocking it, because you are behind NAT or because you didn't port-forward your server and didn't make firewall rule so given port can be accessed.
