Problems with network drivers or a network card can also cause these symptoms, and when clicking on Join from the main menu, an error about network initialization. In this case, it should help to reset your network adapter (instructions below, if required), but since the game was working fine, an issue with a firewall program seems more likely.
- click Start (or Search in Win 10), type cmd into the search box, right click Command Prompt and select run as administrator. - type the following command and hit Enter netsh winsock reset - when that is done, there should be a message 'Winsock reset completed successfully' - type exit and hit Enter, then reboot your computer.
