Thanks, Mark! This is all resolved now, but I thought I'd clarify in case anybody is following the thread!

If you're moving from Beta 3 to the full CSK2, start from scratch! Create your website, database, and user from within DotNetPanel, and then what I did was click on the CSK2.vsi file locally to install. When that's complete, use Visual Studio to start a New Website using the CSK2 template... and after a few minutes it builds the whole thing for you! Then Debug > Start Debug and it will go through another installation process for the database -- I selected my MS SQL database on Ultima Hosts, and it completed a perfect install.

Mark and Ultima Hosts... you rock! Thanks!
