I just had this problem and then found the solution, at least for me. I'm using Windows 7 and Pro-Tools, M-Powered Essential. The program comes with the KeyStudio set that includes a midi keyboard and microphone/headphone USB dongle. Downloading all of the latest drivers and the latest release of the program did not solve the problem. The problem was that Windows was not recognizing the Fast Track driver; apparently it is part of the M-Audio microphone/headphone dongle that comes with KeyStudio. I went to Device Manager, where the dongle was listed as USB Device. I decided to update the driver. I did a manual selection (automatic just installs the same one), selected M-Audio, and then FastTrack, which I had already downloaded and installed. Beautiful, it worked! Apparently it doesn't get applied for some reason. Hope this helps. I thought maybe the KeyStudio keyboard was required, but no, it runs without it.
