I've got the same problem. Just purchased V3.0, running on Windows 2000, Dell laptop to burn the disks.
I have downloaded several ISOs, use File --> Advanced --> Write ISO Image to a Disk. It selects the file & drive, starts burning the CD, then just quits. The last message on the screen was the popup box saying "Writing Lead-In/Lead-Out". The progress bar is about 30% across, then the popup disappears.
I've mounted the CD on both the Windows box and a Linux box. Have tried to open some ReadMe, HTML, XML, Txt files -- some work and some give error messages (Unexplained error, etc). Some sub-directories open OK, others fail.
Some of the ISO images have checksums supplied, and these verified correctly, so the image on the hard drive is valid.
