Considering the About window tells you that Podner is registered, could you tell us how Podner is indicating that it's unregistered?
Even if Podner is not registered you should still be able to see the entire video in the Podner window - unless the Flip4Mac WMV Player Pro component has somehow come to think of itself as unregistered. In that case, you would only be able to see the first half of the movie. Maybe that's the part that's come unglued, and you're seeing that the WMV Player is in trial mode because it puts a scrolling message stating that on the video displayed in Podner. Is that a possibility? If so, Telestream, the owners of the Flip4Mac family of software, can help get you back up. You can visit their support resources at
http://www.flip4mac.com/support.htm , and contact them from there if necessary.
Please let us know whether the Flip4Mac Player idea is spot on. We need to be sure you're up and running, and if that idea is a dead end we can keep troubleshooting with you until this issue is resolved.
