Color palette turns black

Hi

I have a problem with the color palettes. When I am using the Draw system the color palette suddenly turns black with only the red and blue colors available. Also sometimes it comes up with a Microsoft Visual C + + runtime error and CorelDraw closes down. 

I have tried patches and updates but it says my system is not found on my computer. Even thoug I am downloading the right build number.

My computer is a HP Envy 64 bit 7i QM with Windows 8.1.
