An empty white box is blocking my PDF
Starting several days ago, an empty white box now blocks my PDF 1-2 seconds after I open Adobe Acrobat DC. Even when I open the desktop program by itself, without selecting a particular PDF, a large, empty, window blocks my Acrobat screen. The only option allowed by this box is to close it as a window. However, when I click to close the window, Adobe Acrobat closes entirely.
I have tried:
1) logging out of my creative account and logging back in
2) going to "%appdata%\..\Local\Adobe\OOBE\" and deleting the "_LicenseAgreement.xml" file
3) uninstalling and reinstalling acrobat completely, several times
The blank, white box still persists. I am not sure how to proceed further.
