Thank you Robert.
I have discovered that the nature file works and stays but my own video just disappears.
It was what you suspected the video itself.
I have another problem since i upgraded to the latest version.
When i load the Power Director software i get a "OLR Submission" error saying "Resource file not found please reinstall application".
I have reinstalled the whole software gain but once the upgrade is installed i get this meesage.
As you know I am using windows 7 32bit operating system.
Is their something i should be doing to get rid of that message. At the moment it seems just cosmetic...but i am not sure if there is a problem.
Many thanks for your help in this matter.
