From the log it looks like its running ok. Looking at your minion.xml I think Minion is some how positioned off the viewable space on your desktop.
If you're savvy enough...
1. Quit Minion (double check the Task Manager that is no longer running).
2. Open your minion.xml in a text editor and remove the following lines...
Code:
<position height="688.0" width="1204.0" x="1935.0" y="330.0"/>
and (if you have)...
3. Save the minion.xml file.
4. Then start Minion again and hopefully it will go back to normal.
If the above steps seem a bit daunting you can just delete your minion.xml and restart Minion and it will reset Minion just like when you first installed it.
