I sent a digitally signed contract to a client for her electronic signature. I created the document on a PC and am able to sign it electronically (as a different user) on a PC. When she tries to sign it on a mac, she gets an error message. Since I have already signed the contract as the first signer, I can't remove the security, and I don't want to give her the owner password to edit the document. She has not been able to tell me which version of Acrobat she is using. Are there any solutions to this, other than having her find a PC to use? A screenshot of the error message is attached.
Thanks.
