Corel PaintShop Pro X5 shows error

Hi,
Corel PaintShop Pro X5 is a good program that I have been using for months. So I thought I needed to do an update to get latest functionalities. But all attempts of updating have been futile because of the error shown below. I have never seen such an error before so should I just ignore the update?
