I have been using Adobe Acrobat 8 professional with windows 10 till yesterday. When I updated window 10, the Adobe start asking to activate the software and I can't do it via the internet or phone. What should I do to continue using the program.
Acrobat 8 is not compatible with Windows 10, so such problems are to be expected.
You can try running it in Compatibility Mode, but that's about it.
