I'm not sure why it happens so far.
Not sure if you mentioned it above already, or at least I did not find it:
-Did you try to allow Minion in your antivirus whitelist?
-Did you try to run it with priviliedged rights / Admin rights already?
-Did you update your Java JRE installation recently (check your start menu for "Java" folder and in there should be an "Check for updates") e.g.
I can see that the error happens, from the log file, after the addon "GuildHallButton" is processed.
Try to close Minion, also close the task with the task manager, and then remove the addon "GuildHallButton" from live/AddOns.
Maybe it's a coincidence, but perhaps it raises the error somehow.
