unfortunatly I can't seem to be able to access tool/internet options and advanced to change my debug settings so I can see what I'm getting.

infact, I can't even change my home page now "The operation has been cancelled due to restrictions in effect on this computer, please contact your systems administrator.

I'm still in the process of looking to see what I Umm errr blindly clicked on to lock myself out.

That'll teach me to just click with out reading...

I did read another post in here where they said close everything and run CCleaner twice and try again... didn't workm still can't access the website.

so any help would be greatly appreciated

Thanks
