I just reinstalled windows 7 on my Toshiba Satellite laptop. Before I reinstalled it, the track overview would load, I would be able to see the whole song and it would generate the BPM. Since reinstalling the overview will load about 30 seconds of where the track is currently playing, but will not load the whole thing. To get the BPM to generate, I must play the whole song through. I have tried analyzing the files with my SL 1 disconnected, but there are still some tracks with no BPM.
