We are aware that some customers are unable to enter game servers. We recommend to players that are experiencing this issue to delete and restore the HAWKEN.version file.
If you have the HAWKEN launcher icon on your desktop:
Right-click and choose “Open File Location.”
From here you can delete the HAWKEN.version file.
If you do not have the HAWKEN launcher icon on your desktop, the default path to this file is below.
Start -> Computer -> C drive -> Program Files (x86) -> MeteorEntertainment-> HAWKEN-> InstalledHawkenFiles -> Hawken.version
After you deleting this file, open the launcher and sign in. The game should then patch to the most up to date version.
