Cyber_Hero,
Can you run the file through OVF tool to make sure it is 0.9 or 1.0 compliant? If it shows as compliant, I would need to see the logs to know why the parsing failed and the XML of the OVF itself.
If you don't want to post that publically, it would be best to create a Support Request and provide that data.
Best Regards,
Jon Hemming
