[Plugin: Download Monitor] someone is chaning things

I have been using this plugin for some time and now notice in the logs that status indicters (I guess) are looking strange. I have been receiving “File not Found” and “Redirected to remote file” (I have no idea what that even means…

Anyway, I have also noticed the web hosting account running out of resources while it looks like the files (church sermons) are being downloaded like crazy.

Help, any ideas?
