xml versions not supported

Okay thanks Tim, I do have FCPX 10.3.4 on a laptop so can use this route for now.

Unfortunately there isn't much we can do to help with earlier XML versions, the structure of the FCPXML changed significantly between V1.5 and V1.6 and there is no support for the earlier versions in Worx4x. If you are unable to upgrade your FCPX on the production the only thing that I can think of as a suggestion is to load the FCPXML on a different machine which is running the latest FCPX version and (after checking the project) re-export as a 1.6 or 1.7 XML.

Having a problem using Worx4X, getting error messages about .xml
incompatibility. Exported a final edit as both .xml versions with the following error reports:

Happy to help diagnose the issue if required.
