Error # 10061 indicates no connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running. Do you have a firewall? If you have a firewall and are not sure if that is the cause of the problem, you could (temporarily) disable the firewall and see if you can make a connection.
The error could also be cause by using a proxy server to make your connection through.
