WOW! Nothing happened with the space bar (which I had tried a number of times before, BUT….the #1 did the trick. The arrow still doesn’ work, but the # is great

Thank you so much for spending time and helping me.

Here is the data you asked for. Everything worked fine until yesterday. I will greatly appreciate it if you can help. BTW, I can export to RU and create a video that plays fine.

Thanks again!

I uninstalled and reinstalled AE. All buttons on the preview panel work except the (center) play button.

Preview non working. I created several new videos. The preview button will not work. On existing videos it will work, and it works on sound. The return to beginning arrow works, and if I move the timeline the video works fine. All of my figures are PSD files.
