How to post an image in the forums.

Have you tried machine Restart (not Shut down).
Have you tried IE restart with clear temporary files & cache.

Have you tried Internet Explorer > Reset all zones to default level &or IE > Restore advanced settings.

Re: security certificate not valid

Please make very, very sure that the date (especially the year) in your system clock is correct when you first start your PC.  When invalid certificate errors appear on many different sites, it is almost always a problem with the system date being wrong, which tricks Windows into thinking that valid certificates have passed their expiration dates.

the time and date is right, I have tried restarting, defrag, and security scanning
