A few days ago, I started receiving a 'corrupted file' message after I add and save some comments to PDF files. It began just after an Adobe Reader update so the first thing I did was to reinstall it, but the problem persisted. So, I tried to install another PDF reader called Foxit, but still the problem persists. Finally, I tried to create a new PDF document out of Boxcryptor folder and and after making several comments on it, the file is still good. I think Boxcryptor is damaging my files, and it has never happened before.
I found this post with a similar problem, but the link for the solution is broken: https://forums.boxcryptor.com/topic/file-saved-into-boxcryptor-corrupted#post-3476
I'm running Windows 10.
Please, this issue is ruining my work
