Most of the time when you generate stress iso and encounter errors like the error you encounter is something problem you made while you set the I-configure. What I mean is something lacking or not properly set, that is why errors exist when you generate iso.

I will ask you if did you set I-configure first before you generate iso?
How did you set it?
Did you provide another program & free ware as a pre requesite for I-configure setting such as updated VoloView Express and sssplt30.ocx?
