I have been experiencing EW 6 freezing and unresponsive a couple of times. It usually happens when I have videos loaded into the schedule. Any idea why this is happening?

Make sure you are on the latest Build 6.7.14 of EW6.

And make sure you have installed the additional Video Decoders as per this support article.

And make sure your computer meets or exceeds the System Requirements outlined in the following article.

See if that helps and let us know if it doesn't.
