It would be better to update it because their is no support for the older versions anymore^^ , for the pinging try to troubleshoot your firewall . Try to ping from target_ip to source_ip (opposite direction).
If you have response in any of 2 cases above, check the firewall on your target machine (or as in your case, for Windows, make sure you are connected to Private Network, not Public). And make sure you are trying to ping the proper IP address.
