Hello Djinnin,

Please turn your router off for 15-20 minutes and then restart it. Once its back on please do the following:

- Click Start, then Programs, then Accessories and then locate Command Prompt
- Right-click on Command Prompt and left-click on Run as administrator
- In the Command Prompt window that has appeared type: ipconfig /flushdns
- After typing the above command, press Enter to execute it and then close the window

Once this has been done, test the game again to see if the issue persists.

Please close all unnecessary background applications running on your computer and then test the game again to see if the issue persists.

You can do this by either closing the programs manually or using Selective Startup:

Also if you have the possibility to reinstall your anti virus software, please remove it completely and then commence testing the game.

Doomsinger,

Safe Mode is not going to help in this case as you cant play the game in Safe Mode due to most of the devices being turned off.
