I am trying to do a music dvd but it says cannot identify with chapter points, this has happened before with some music I try to use with the program. I dont really know what version I have, do I need an updated version? It there a version that can fix this bug.

Not used it personally, but I am sure it would say what version in the about box or similar. Then if you don't have the latest version, just download the update and see if it helps.

You could also try DVDFab as a freeware alternative. If you want it to work directly from encrypted originals then you will need to install a plugin.
