XML is your friend. Always take an XML copy of a project when trying to open a Final Cut Project from one version to another as the translation is more likely to work. To make an XML file, control click in a blank space in the browser and ask to export XML and choose the most up to date version.
It is good to unnest any sequences before exporting any XML file.
