Hi,
Follow these steps:
~ Open the region list, select all regions that you want to burn to CD
~ Select Bookmark->Export Region(s) to Folder
~ Now load these files to Express burn to start burning
Hope this helps. There is a bug with the Bookmark->Copy Region(s) to CD option in this version, we are fixing it. Once it is fixed in next release, you can use this option instead of following the above steps.
