I just installed movie edit pro 15 and was showing my wife the visual effects. I went to make the screen bigger and was brought to a black screen I went back and found that the bar controlling the playback function had vanished. I forgot what else I did after that but whatever I did made the whole edit section then go blank... nothing comes up. I tried uninstalling then reinstalling the software but the same thing happens... should I try making a video and maybe the edit function will come back? I'd appreciate some help/advice.
