I would suggest posting a link so that we can see if the files are in the right location. Also, doesn't wordpress have a support site? I am not try to drive you away from the site, but if they have a support site then I would think they would have members familiar with the software.

I have done extensive research into this and haven't found the cause anywhere on the official wordpress site, I'm just posting around to see if I can come up with an answer.
