Blank page when tried to open Fluid scenario creation or Part design

I created a 3D model in part design and tried to work on Fluid Scenario Creation. I have almost achieved to do it, but then I saved the file and closed it. Now I am trying to open the Part design or Fluid scenario creation but all I see is a white blank page stay for hours(either to continue previous work or start a new session). I also tried to uninstall and install complete application but still is the same case. What should I do to make it work?
