Can't run nodeXLPro

After uninstalling NodeXL basic, we were able to get NodeXL Pro installed. However we are getting error "you have reached the maximum number of offline opens" ? Please advise.

NodeXL need to communicate to the server in order to validate the license. This message means that NodeXL can not communicate with the server. There is probably a firewall blocking the application. Either add a firewall exception to NodeXL or disable the firewall. Users have reported that some firewall block ICMPv6 calls which is used to ping the server. Please take a look and allow these calls for NodeXL to validate the licenses.
