I have had Power Drector 13 for about a year (and another version for several years) but have not done much on it yet. When I have used it, what I did worked just fine. Today, not so much. I have put pictures and video on the timeline but can't preview them. When I click movie and click the start button, the "guide" that moves along the pictures (I'm sorry but I'm not a professional and use this only for family stuff so I don't make myself familiar with the lingo) will start moving but nothing shows up on the preview screen. I am in major need of help because this is for my granddaughters school project that is due tomorrow. Thanks!
