You should be able to uninstall the app and then reinstall without paying again right? Since its on your account? If so then that should give you the new version. Don't uninstall it until someone else verifies this, I don't want to be responsible for you losing it lol
The new version of Beautiful Widgets is not available on the Market Place to update to. I had a backup of it which I manually installed using Astro.
By the way, Swype is simply awesome. It is now my permanent v-keyboard on my droid. Love it.
