Socket Errors are most likely caused by a terminated connection on the Host Machine.
This means that something is affecting the connection between your computer and the servers running the HGW file watcher, Xtrap or the Game.
1. Almost always this can be corrected with patience and by waiting until the initial rush for updating the game is over.
2. Other times this can be corrected by restarting your modem/router or flushing your dns and checking to make sure your connection is stable.
3. Also try to use Google to research the particular socket error you see. The error message can often times be searched to give hints to it's solution.
4. Finally always try uninstalling and reinstalling the game. If the connection was broken during an update some of the game files may not have patched properly. This means that an uninstall and a reinstall may be required.
