Hi Bill,
The encrypted strings are the connection strings, so your hunch is correct. I have forwarded your question to our internal support alias and hopefully someone will respond in the next day or so. The simplest solution may be to uninstall and reinstall, but let's see if one of our tech staff have a better alternative first. Thanks for your patience over this Thanksgiving holiday.
More info from our Support team:
Please try to reinstall using the account that will be used. The installer should encrypt the credentials and store them in web.config and there’s no way to do that manually (hence the re-install).
