I think slimowski is right. Your log indicates that you are not allowing any preferred server functionality: 2014-04-02 17:40:07(1236-1232) maptopreferredhandler.exe:Mode - Require Direct, no preferred server.
The result is that you need to have a preferred server that matches your source exactly. In this case that would appear to be tech. Do you have a preferred server entry for tech (not tech.whatever.org or anything, just tech)? If not, you'll either need to add it or you can just allow the tool to use preferred servers and it will find the closest server that has the image file and use it.
