I'm using a PC with Windows 10, and Web Designer Premium v. 19. I upgraded to v. 19 after my computer crashed and I lost all the files on my hard drive, including all my web pages. I had my old CD-ROM, but of course that was v. 12 so I had to buy it all over again. This is the third time I've purchased Xara Web Designer Premium!
I downloaded the Jewelry Online Shop from Modern Business Website from the Online Content Catalog. The template only has 2 pages. So I clicked "new page" in the page and layer gallery. Immediately I got an error message (screenshot attached). When I clicked through that, I got "a spurious error has occurred" box (screenshot attached). Now I don't know what to do, as it appears I'm not allowed to add any new pages. Another $50 down the bottomless Xara drain.
