thank you very much for your generous offer to help me online. It's a very nice kind of you, a really great service.

But meanwhile I found the solution right here at the SF-forum: http://forum.strataframe.net/Topic211-10-1.aspx

The path to the SF Addin.dll pointed to the wrong direction, directories named in english on a german XP. This can't work, but is easy to fix if you know where to look at. ;-)

Thank you very much for your great support,

Ralph

I'm glad you found it, Ralph.  There really is a great deal of information to be found here on the forum if you know where to look
