Try using the Custom Assembly Tab and read each individual track into the Track List Make sure you import them in track # sequence; 1 first, then 2, 3, 4, etc. so they match the track # on the original disc. When they are all in, click the Write CD button to write them to a blank CDR disc in your CD Burner.
Microstudio V2.303 will be available next Tuesday. This has a new Import Tracks Tab that will allow you to import all the tracks as individual track files, then add them to the Project in the Custom Assembly Tab with one button click. That will make this operation much faster.
