On a MBP 2.2GHz, 2 Gb RAM, Leopard 10.5.1, CDRevol 1.1.2, CD-R Sony Supremas, 700Mb

I'm trying to duplicate my kid's precious Mika's music CD, wath was impossible with Apple disk util., nor with Toast.

No problems to create a proprietary image disk with CDRevol., but everytime I'm trying to burn, it says " checking for blank CD" ! And turns around during hours .... !

Up to now, I'm unable to burn any CD, and that software seems to be unusable for me?
Or is it a limitation for the dema version, not to be able to burn? But it was not documented!

Help from anybody, somebody, or the creator/developper (I didn't find a contact email on their site :-(( ), please !

I was enthousiastic, I'm disappointed.
But I could change my point of view,and relay it on this forum if I misunderstood something ... or if I receive some help from the developper.
