I used Daylite in the past and am interested in coming back, due to a change in employment and new needs. Is there an upgrade price? I cannot locate it in the store.

I have my license and serial number.

In the store, go to the Daylite Productivity Suite page; at the end of the product description, there is a link titled "Looking for Daylite alone?" - this will take you to the Daylite page where you can purchase an upgrade license.
