I had problems with this unit from the start.  Anything I tried to do produced a  "System Error" pop up message.  That included trying to access files from a thumb drive, download photos from a digital camera, and other similar things that are routine.  I went on a live chat and spent about a half hour with "Enrico".  During that half hour something improved so that I could pull up photos from a thumb drive, but the CD drive still wouldn't work.  Enrico finally told me I'd have to take the unit to a local repair shop.  Why?  I'm simply returning it instead.
