Urgent - Unable to find asset portion in asset - Deadline 31 december

Martin,
it is very hard to say why that is happening with just the screenshot. Please check the position on the timeline and see whether there is anything odd about the clip at the time mentioned and if not then please post the fcp xml so that we can check it for a problem.
