Does the file 'hfs.events' show up in the root of your hfs folder on your drive? It should. If so, open with an editor like notepad, or use Alt+F6 from the HFS gui, to see if you can spot the reason why it isn't being read. Still no idea - delete the hfs.events file from the pc it isn't working in and let HFS re-create it with Alt+F6. You are using the latest and same build of HFS on both pc's aren't you?
