I just installed Minion Yesterday and it ran fine. Today when I launch it, it just sits there with the loading icon. Eventually, it times out. Here are my minion0.log and minion.xml files. I figured you might ask for them.
Are both the detected wow games on your C: and F: still accessible? Interesting theres no errors in the log.
Can you try renaming your minion.xml and see if it gets Minion working for you again? If it does work for you after doing that restart Minion again and see if it still comes back?
