I've attempted to re-activate the software 10 times now, including after two full reboots, but I get an error message (Code 160:41) every time that says that I must be connected to the Internet for the activation process to work. The 'Activate' menu option is occasionally grayed out, but when I try to print a document from a website the activation dialog pops up. Since then, my copy of Acrobat 8.0.1 Standard has warned me that I must reactivate it within 5 days or I won't be able to use it.
My laptop updated to the Windows 10 Creators Update last night.
