I was having problem getting my my CD Spin Dr to play back after recording, this sucked. The program would do everything but play back. I did have the update for toast 7.1.3 so I installed it put in my App. file now when I open Spin DR it couldn't find toast 7. So I replaced the 7.1.3 toast only with 7.0 kept the spin dr update and everything is working. I am using Mac G5 PC OS 10.5.8 I hope this will help anybody who might have the same problem.
