James Wilkinson 0 Report post Posted April 7, 2020 Nitro Pro 11 (11.0.1.16) on a MS Surface Pro with Windows 10 was working fine for over two years but today it won't open a window for any pdf file. The icon is there, in the task bar, the file name is there, but the window won't open the so I can see it or work on it. Any thoughts about how to remedy this so I can see and work on my pdf files with Nitro Pro? Share this post Link to post Share on other sites
