EvBarney383146,
As Office guy pointed out, the issues seams to be with a Virtuosoft
try removing the Virtuosoft extesnion from the extension manager.
The referenced in the error is likely in the Users configuration folder instead on the Dreamweaver Configuration folder.

Brad,
The "Initialize UI is not defined" error will be cleared by deleting the Dreamweaver Cache file from the user configuration folder as outlined in Office Guys post.
