Importing a Corel Central calendar into WordPerfect Mail

I just upgraded from WPO10 to WPOX3. As best I can tell, there is no way  
to import my CorelCentral calendar into WP Mail (the former allows you to  
export to a vcalendar or text file; the latter will only allow you to  
import an icalendar file).  Is there any utility available that will  
convert a vcalendar to an icalendar file, so that I can import it into WP  
Mail?

Thank you,
Terry
