Jack,
You need to download SQL Server Management Studio Express -
http://www.microsoft.com/downloads/d...displaylang=en. Go to that page and scroll down to the bottom. Select the
SQLServer2005_SSMSEE.msi and download it.
After you download it, run the installer. Then launch the app. You should see this window, click connect.

Download the attached Word .doc and start on Page 9 (Fixing the login for the databases). Do those steps for the DToolsProducts50 DB and any other that requires it. That should do it!
Thanks!
