I am having an issue with module automatic upgrades, and it's all of them, not just one. This is what I get:
Downloading update from http://downloads.wordpress.org/plugin/my-category-order.2.7.zip
Download failed.: HTTP/1.0 404 Not Found
I had a hard time running the WordPress automatic upgrade module, it asked for my FTP credentials, so I'm thinking it's a permissions issue. It's a godaddy hosted blog - I used the automatic installation tool in Godaddy and then added my mods.
