Frank,
I regret to say that our demo is about 5 months old, and we have had very significant upgrades. The Plextor 1210 and 1610 models are supported in Microstudio V2.303 and higher, not in 2.103.
We should have a new demo of V2.311 on our website around the end of next week, or early the following week. Our full release does work with the Plextor drives, as they are what we buy, test-certify (we reject the drives that fail our tests), and sell.
Please read our notes on CDR drives NOT working with CDG, even though they SHOULD do so. This is at:

Thanks for testing with us and posting your question.
