Unable to parse FCP XML

I reimported the faulty xml and got this error from FCP:

PIX LOCK V1 AAF export.fcpxml Encountered an unexpected value. (tcFormat="DF": /fcpxml[1]/library[1]/event[1]/project[1]/sequence[1]/spine[1]/gap[2]/asset-clip[119]/@tcFormat)

Now if only I could interpret what this means!

Here is what the error says:

Unable to parse FCP XML file to obtain project information

Details:
Extracting Audio
No ref attribute found
Parsing FCP XML
Parsing FCP XML document
Parsing audio element

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 a Library or Event;
- Ensure that this is not an empty project (or that all audio is disabled);

X2Pro Audio Convert 4.5.4

Any way I can trouble shoot this on my own. Not sure what to looks for as the problem.
