If you were able to play the game very well , but can’t connect to the server after a patch or minor patch added to the game (can't connect to the server , even if you got the latest manual patch), you will have to do the following things:
1. You will have to Clear out all the wokf folder.
2. You will have to Disable your firewall and antivirus .
3. You will have to download the client from our website :
Here will be the link after the host is ready!
4. Start up patcherkf.exe and update .
If the launcher still say : "cannot connect to server", that means you did not completely disable your antivirus , not all antivirus programs are designed to work compatible with operation system . So your windows Security Center may always alert your computer is under risky of virus , but actually your antivirus is working without antivirus icon at the lower right corner of your computer screen . Hence you should find out the solution to disable your antivirus , we suggest you type “Disable antivirus name “ into the google search toolbar . i.e. If you are currently using or used to install McAfee , you should type “ disable McAfee “ , then dig ,dig ,dig .
