- If you are running Windows 7, ensure that Windows is completely up-to-date and there are no updates waiting to be installed. Fully update Windows, then try again.
- Please check to see if you have MSI Afterburner or any other graphics card over-clocking or “boosting” software. If you do, try disabling or uninstalling it and try running the game.
- Try temporarily disabling your antivirus or other security software and see if that allows the game to run.
- Try reinstalling your Steam client. Also delete everything from your Steam install directory except for steamapps and userdata folders.
- Check your Steam connection and make sure your status is set to “Online.” Frequently the cause of loading screen problems is the Steam authentication server going down.
- Make sure the build has downloaded properly. Right-click on the game in your game library, select Properties, go to the Local Files tab, and click Verify Integrity of Game Cache.
- Try opting out of Steam beta, especially if you are using a Mac, as the Steam beta Mac client can be unstable.
- Make sure firewall is not installed, disabled, or turned off. Make sure port open from 5055 to 5100 for outgoing traffic.
- Make sure that you do not have any 3rd party VPN or networking software, such as Hamachi or Tunngle, installed or enabled, as these are known to route traffic improperly or poorly.
- If you are using the Killer e2200 PCI-E Gigabit Ethernet Controller (NDIS 6.20), you may need to change its settings. After opening the game, from the “Applications” tab of the Killer Network Manager, click on the Guns of Icarus Online process. Switch the priority from 1 to either 2, 3, or 4.
- Make sure that your internet connection is working properly and you are able to access other online services or sites without a problem.
- Make sure that your firewall or other security software is not blocking outgoing UDP traffic to remote ports between 5055 and 5100.
- If you are using a Linksys WRTS router, try upgrading your firmware; this will frequently solve connection issues with this router.

The log file is cleared automatically each time the game application is started, so if you have something to send for a particular bug, you’ll need to grab the file before you open the game again. When sending your log, please attach the file (do not paste the text in the body of the email).
