Barry, your problem is trying to write at higher than 6x rate. As Brian Corr pointed out, your error message is exactly duplicated in the Tech Support Catagory at:

Click your Microstudio Drive menu (at the top) and select the Drive Speed function. Set your write speed to 6x. It should work.
Microstudio 2.2 has fixed this problem. We expect to release it before the end of February.
