Question
Digitally sign greyed out, worked 2 weeks ago :-(
Trying to digitally sign a PDF doc. I was able to do this 2 weeks ago, but can't now. I've tried using the trusted certificates (under tools) as well as "fill & sign" and both are greyed out and won't allow me to use them.
Screenshots provided of what version windows I'm using, etc.
Thanks in advance for your help
