I am using windows 7 ultimate and latest opera version that was downloaded from opera official website today.

Opera is not running properly on my computer.
It does open the browser window but it shows no content.
Instead it shows only black blank screen.
It makes opera completely unusable.
I tried to uninstall and reinstall it but with no luck.
Does anyone has any idea?
