Pity you decided to uninstall the program as a re-install will not have all the updates you may have downloaded in the year. You should have been on version 17.

Paste %localappdata%/Xara/XtremePro/16/Cache/designs/eng/ into a MS Windows Explorer address bar to see if you have any remaining content.
For instance my Designs folder is 3.08GB.

Let us know what you have.
