very weird, not sure what to do.
Maybe add http://www.ofncommunity.com to trusted sites - doub it will work, but no harm in trying.
in IE, click Tools > Internet Options > select Security Tab > then click Trusted Sites, then the Sites button just below it to the right. then type in http://www.ofncommunity.com and click Add.
you can also add the URL in Privacy settings.
Good luck!
