Are you on Windows? If so go to start then run... type in cmd and press enter.
You'll now have a command prompt open. Type:
ping
www.marlinownersclub.com
What this does is finds the server and see if it responds to you. Select it copy and paste on to here (you may need to right click with the moose to be able to select and then copy)
Second think you can do is a trace root with the following command:
tracert
www.marlinownersclub.com
What you can do with trace root is see where the traffic is going from you all the way to the owners club server. If it's doing something wrong on the way it may be possible to diagnose the issue.
