It renamed the folders

Thanks for the report.  And be assurred, an updated firmware is being worked on at present (altho unknown if it would help prevent the issue you had).  

On my own front, Windows 8 has spontaneously rebooted my computer at least 3 times in the last 12 hours, closing everything I’ve been working on in the process–and I hadn’t done anything to my system.  Computers–sigh.
