I have a problem getting into the security site on the
internet. For example, I tried to buy airline tickets on
line. But I will get a message said that "this page
cannot be displayed". I talked to my internet provider
SBC Yahoo DSL and we went through step by step process on
the computer to try to solve the problem. Finally they
said it is my OS that is not letting me to get into the
security site. I have a hp pavilion ze5200 notebook,
designed for Microsoft Windows XP. I am wondering if you
can help me with this problem.
