This is a bug in the Software. All you have to do is click the Down arrow on the Right hand side of the Reading Drive. Left click the where it states the Plextor drive on the very bottom. Then it should close the Listbox. Then close Microstudio and Reopen it. It should now work.

This is the only way to fix this, so if it doesn't work, do this again.
