Thanks Jason. I was able to start DWVR. Of course, now I'm at ground zero with ALL extensions, but that's a good way to get the job done that I need to do now.
As for the future of the WA extensions, I will learn when the time for re-loading comes.
(BTW, even though I clicked the 'Email me with all replies to this thread' when I posted, I didn't see any email. Would it take more than 3 hours for me to be notified?)
