I have had Acrobat 8 Professional for a long time and used a lot.
Now it is asking me to Activate it again?
Don't know why?
I can't use Adobe Acrobat 8 Professional now...!
No, you can't. Use the link above to get a version that doesn't require activation.
And DO NOT post your private contact details! You're asking for people pretending to be from Adobe to contact you and scam you.
Don't trust anyone who suggests to do a Skype session or whose user-name does not have the Staff icon under it!
