When I open Bookmarks,Downloads,Extensions or History it shows me nothing with a leaf in the background. How can I fix this or go back to using an older version?

Since updating Opera and my computer Opera is not working right. I try to go to my history and my speed dial opens up every time unless I reload opera 35. I also have problems with some other sites not working right with Opera 36 now.

How do you reload Opera 35

I can't open History,Bookmarks,Downloads,Extensions.

When I open them I get a empty screen with the wallpaper.
