Tim,
I'm wondering if you meant "can't delete any files", because "can delete any files" is a normal operation. The file "tags" (attributes) r, w, and d are read, write, and directory (x for execute is missing here).
One possible explanation, not verified in any way, is that Rootsweb is starting their process to make Freepages read-only, and this particular county has been caught in the early stages of this process. This is just a guess on my part - I do not know that Rootsweb has started the process yet. I was able to get into my site on Saturday, and still make changes. I don't remember my Unix/Linux rwx attributes well enough to know if you need execute permission to be able to delete a file/directory.
