recover rendered files

[steadi]

Hi, I've a problem: I've a 20 slideshow-project. After full rendering of slideshows and menus (6 hours), at the starting of Burning of DVD disk (or DVD folders, or UDF ISO image), there's an error, the program crashes and I'm forced to close it.

Now I downloaded patch file and I'm trying another time, but.. is there a way to recover yet rendered files, and continue only from DVD burning without re-starting to render all slideshows and menus? I've seen that all audio and video rendered files are on folder Documents\Ulead CD&DVD Pictureshow\4.0

Thank you.
