Resolved internet options gives restriction message

In g-mail,I get the message that my browsers cache is full...etc.When I go to int. options,I get the restricted message.I am the administrator and have tried several things from the internet to no avail.I'm running windows xp home and int.expl.7.I'm about to go cross-eyed.Can you help? Thanks, Bob

 

I tried all the stuff that was recommended,but got nowhere,then I thought what the heck.While I'm waiting for some more suggestions,why not reinstall the XP disc.It took awhile,but works like it should now.Got my firewall back,internet options,etc.I ran registry mechanic again and it was like getting a good laxative!! Please share with others who are having this problem. Bob
