Unable to parse FCP XML file

Please attach your fcpxml

Hello,

i have this error
Unable to parse FCP XML file to obtain project information

Suggestions:
- Ensure that the file is not locked by another application and is readable;
- Ensure that this is a valid FCP XML file from a released version of FCP X;
- Ensure that this is the export of a Project, not of an Event;
- Ensure that this is not an empty project (or that all audio is disabled);

Exporting from final cut pro 10.1.3 an XML and X2Pro 2.1.9

I don't know what can I do?
