      Hi Christos,
      I have Windows 7/64 bit Professional but have not tried running in xp mode.  As I found more about the limitations of  the virtualization layer I concluded it would not work as expected when working with applications that require specific devices to be available. All the drivers including sound cards are emulated as a generic device so your Delta card or whatever appears as a generic sound device. Something else to consider is that xp mode capabilities are part of the Professional or better versions of Windows 7.  Windows 7 Home does not come with the virtual box.
      I have not tried your latest trial version with windows 7/64 bit. The last time I looked  at earlier versions I was experiencing tuning issues other folks were seeing with later firmware versions of the USB2I2C. Rocky with I2C tuning was working so the drivers are OK in 64 bit (in test mode that supports unsigned drivers).  I will give it another try once I get a chance.

      "XP Mode" only comes with Professional or better.  However, you can run VirtualPC under lower versions of 7, even under Vista or XP.  VirtualPC runs much better with hardware virtualization support, of course.  I believe, though I have not tested this yet, that VirtualPC requires virtualization for USB to emulate.  The difference is that you need a valid license for XP to run this way.  You can get a valid "test" image of XP from Microsoft, if you agree to their license terms for its use.

      I actually had to do this at work after they "upgraded" my machine to IE 8, which broke my ability to access some work functions that required IE6.  I installed virtualPC (on XP), with the test copy of XP/IE6 from Microsoft.  Now when I need to access that site, I load VirtualPC, boot the XP image, and I have IE6.... yeah, it's ugly, but it works better than any of the mutiple-ie workarounds I tried.  And even without hardware virtualization support, it runs tolerably well, provided I am not running too much on the host machine.

        Mine brings up an email blank with 'Unsubscribe' as the Subject. I
        suspect you just have to send that as it already has an address and your
        email address would be added to finish the job once you send it.
