I have tried the registry trick, but the program fixes itself periodically, so it may not work indefinitely. A rough trick is to delete or rename the "C:\Users\...\AppData\Local\Xara\XtremePro\11\WebF iles\ENG" folder (path is a bit different for different versions) which contains the URL to the actual nag screen on the net. Here again, the program fixes itself after a while, so automatic countermeasures are needed to ward off this nuisance.
