My chief charged with me to create many slides presentation in a week. I've created a half of number of slides for today. Only ten minutes ago, I opened my .pptx file again. It appeared that some slides disappeared from it. I used pptx repair tool from Microsoft, but nothing changed. I used Google and Yahoo to find something, but I didn't find nothing great. My ideas for now are finished, Microsoft couldn't assist me. I hope I have chances to get my slides back, isn't it?
