Yes, but 2 boxes arent a sufficient data-base to make a profound statement. But on all of my boxes since 2003, when i bought my MD-Device, i had several problem with the NetMD software (BeatJam). On some boxes it worked without a hassle on others i got program-crashes or bluescreens. Btw, the Net-MD-driver on this forum seems to exactly the same driver as on the BeatJam-CD. This driver was released in 2003. The Sharp-Homepage does not offer anything for download except users-manuals.
