When I click on contacts to read my messages I get kicked out.

I joined a couple of days ago and found one of my skydiving friends. I sent him a message and he wrote me back, but I am unable to read what he has written. when I click on "Contacts" a pop up box showes up and says "Internet Explorer cannot open the Internet site http:/peoplejar.com/contacts" "operation aborted". I can view the site just fine every were else but when I try to read my messages it shows me this pop up and kicks me out. Can you help?
