Can't Check UPS Status

Hi,

   I am having a problem using 2 sites, UPS and The Sportsmans Guide.  The problem is when I try ordering something or check the status of a shipment, the page hangs and I get an error, "Internet Explorer cannot display the webpage". 

I order on lots of other sites and no problem.  I have three computers in the house and all three do the same.  When I try it at work, it works fine.

Please Help!!!!!!!!!!!

VR,

Don
