You're on the wrong forum - Xara Designer is not a Vegas product.

In any event, it looks as though MAGIX has sold Xara Designer as it no longer appears as a product on their website. A post on MAGIX's forum got this comment from a forum moderator:

Magix no longer sell Xara products and presumably the 'update service', these are now back with Xara.

You can update the program to the latest version, the Magix versions were 1 or 2 versions behind those of Xara, on the Xara website, there is also a discount for moving back to Xara - see the banner at the top of the Xara home page.

A Google search shows that Xara Designer now has its own webpage - https://www.xara.com/welcome/ - so you'll need to contact them with any enquiries about Xara.
