I would focus on fixing the "wrong symbol" first, there is obviously a problem somewhere. I have actually had this happen to me once before. The easiest way to fix it is to go into your Device Manager, and delete the network interface (do NOT check "uninstall driver"). Reboot after you have done this, and windows should reinstall it. You will have to reconfigure your network settings if they are not DHCP, but it should fix the icon. Then try the game again.
