Query: Quality Control Issues

I'm sure that this is a great product - if you can get the included software working (Rioport Manager.) I downloaded one song to the Rio, but now the app freezes whenever I try to connect.The firmware update program is a joke - still says v1.04, even after supposedly upgrading to 1.15 I use several other USB devices with no problem, but not this one.Diamond MM seems to have an overall quality control problem, even dating back to my Diamond Stealth video card from 1993 - it worked okay, but just try to get new drivers or tech support (same problems back then!)Sorry for the negative review - but I'm looking for a different brand.
