Install in Another Directory, xml-rpc posting, Word to WordPress

I seem to be having a problem with the xml-rpc posting from MS Word to a certain blog.
I don’t have problems with other blogs.

Word finds the site but can’t connect

My guess is that the problem is related to putting WordPress into a subdirectory of the site. I tried telling Word to go to the subdirectory, but then it finds nothing.

Any ideas?

Thanks!
