I installed MS PowerPoint 2013 some weeks ago. During this time I created many presentations. Yesterday one of it when I opened file viewed me less number of slides that I had created before. It happened immediately after my laptop bugged while I was working in presentation. After reboot I got such trouble. I launched repair pptx feature from Microsoft, it didn't solve my issue, I wrote to MS, they haven't answered me yet. It look like my slides disappeared of my poor laptop.
Hi there,
Welcome to the Sony Community.
You would need to get in touch with Microsoft directly for further assistance with this issue.
Best wishes,
