Thanks for the message. I had a similar issue until I rebooted the computer and did general maintenance (repairing disk permissions, for example). Can you try that and let us know if it helped? If not, please supply the community with more info about your system and media in this format: How do I write a bug report?
I appreciate the information you will share and hope to help you then.
Thanks, Kevin
