I have great news.  My former hosts finally responded to my repeated help requests and managed to help me figure out how to get my files off their server.  I tried it last night, and I was able to download all of the files.  It will take some time to restore everything, but the good news is that the blog entries, handouts, Power Points, and all the pages are intact.  I just need to work at getting them uploaded and working with this template.
