Hi there, I have Microsoft Office 2016 installed on a Macbook Air 2013. A couple of weeks ago, PowerPoint started giving me the following message when I try to open files: "Powerpoint has found a problem with content in the file (filename). Powerpoint can attempt to repair the file. If you trust the source of this file, click repair". If I click repair, what usually happens is that several of the slides show up empty. After googling the issue I see that Windows users have found a workaround (http://answers.microsoft.com/en-us/...n/6743da45-2ca3-46e5-b497-573de1dd5d55?auth=1), but I haven't found any equivalent for mac. Anyone else experienced this/knows how to fix it?
