Powertap issues

I'm having issues downloading data from my powertap head unit. I got a new PC from work and somehow it is not recognizing the PT head unit well enough. It starts downloading and then just quits. So I've got a full PT and no data to download. Kinda frustrating but at least I still have some measurement for the workouts I'm doing. Yesterday I did the HOP workout which I simply love and this morning I warmed up for 30 mins and then did three sets of 3x2 min Power Intervals with 6 mins rest between sets. I got to 300-320W on average for the 9 intervals so that was a pretty decent workout. Kinda looked like this...
