I have TOAST 7.0.2 on my iMac & iBook. All of a sudden TOAST 7 , on my iBook will not burn audio cd's. I get "illegal request" message. I've reinstalled TOAST 7 and still no luck. TOAST 7 Titanium is still working fine on my iMac. What's going on?? I've used several different brands of media and still won't burn a disc. HELP!
