The title pretty much says it all. I bought a used unit some months ago and decided to finally get around to adding it to my studio set up. As I dove into the capabilities of this unit I realized it may need an update. So I logged into Line 6's website and updated the drivers and it said there was a flash memory update available, so I did that as well. Now the display just says "UPDATE FLASH". Turned it off and on several times, unplugged USB, unplugged power... no change. Anyone experience this, or have a fix?
