I've recently installed Reader DC on a new windows laptop (running Win 10 Home 2004) and whenever I load a file into the reader and click on it, it becomes unreadable. I can't find any issues that match this. I've reinstalled it a couplle of times and no change. It was happening before I updated the laptop as well. Can't work out how to fix it. Any help appreciated. I've attached before and after versions of a dummy file which shows what's happening. Happens with all files - not just this one.
