PMCD burning blank

[S_fireMastering]

It makes .ddp file and all the documents correctly, i see the % of burning running from 1 to 100% but the disk is empty !!
Nothing writed on it!

Running 3.2 version on osx 10.5.8 and i ve tried external firewire premium2 and internal mac pro burner.

Is the second project that i ve mastered today and it get 6 hours of time!
The first, a 11 songs album, runs perfectly and completed in 30 minutes but after this disc pmcd did not want to work any more.

It' s incredibly frustrating to spend $$ for a so buggy software! I m really tired of problems and ****st rigid procedures to make bugs not happens!

Finally i ve mastered the disc in another studio with an "old" 1.5 waveburner!The same tracks and the same pq marks and xfades !
Incredible

Exuse me for rage but this is really enough
