Cannot see maps or aircraft suddenly

#1
Since yesterday, the data no longer shows on my PC; no aircraft, no aircraft names, just the main titles and a large ad on the bottom right. I checked to see and my PC allows cookies & I have Java. I use Windows 8. What am I doing wrong? Planefinder is my favorite site especially since I had a stroke and am confined at home so I can no longer plane spot. I depend on this site so I can get the action without leaving my house. Please help. Thank you.
