Hello, my question is my version of Adobe Acrobot Pro DC will not let me digitally sign documents. The document is locked by my client and won't let me sign. Could the problem be my version or the document itself? I wish I could upload the document to show you what I mean.
I am sorry there is nothing we could do about it if the document is locked either by password or any other method.
You would have to request your client to unlock the document so that you could sign it.
The documents are locked for security reasons and there is no way Acrobat could unlock it.
The only option is to get in touch with the client and get the document unlocked.
