How do I totally uninstall Corel

I tried to uninstall Corel Draw suite and it never totally uninstalled.  Obviously there is more to do than go to control panel and try to uninstall.

 

I am having great problems with my Corel - Bitstream keeps crashing and my Shaping docker is blank.  Thought I would re-install, but need to do more than I tried.  Any help would be appreciated.
