Reinstalling Corel Draw Suite 11

Hi, I've been having issues in Corel Draw Suite 11 with various things such as copy/paste, memory, and crashes. I can work around these issues but it is time-consuming and annoying. After looking for answers to specific problems and finding nothing that works I've decided that reinstalling Corel Draw Suite 11 might be the thing to do.

My question is do I reinstall over the the existing installation or do I uninstall Corel Draw Suite 11and then reinstall?

Here's what I'm running:
