Update:
I have loaded Windows 7 SP1, and Windows 7 Update and now Reaper loads without freezing, thanks for all the advice.
However, when I try to set my Preferences, Device, I load the MOTU configuration as shown in Attachment 1, as in Attachment 2, but as soon as I click on OK, the computer freezes. Nothing works, not even Cntl,Alt,Del and I have to reboot the computer.
I guess it's progress, but still I can't get Reaper to operate with my MOTU 24IO.
