Unable to sign and save documents

[DLUnleashed]

I have Acrobar Reader DC on my Macbook and iMac. I think it is free and I use it to sign contracts with custom signature and also to write in text, save document send then send back to client. This week I was unable to do this on two separate documents on two separate computers. Which brings me here. Did something change? Every time I try to save differetn documents I've edited I was unable to save all I get is this:

Hi there

We are sorry for the trouble. As described, you are getting the error 'A number is out of range'

What is the version of the Acrobat Reader you are using? To check the version go to Help > About Acrobat Reader DC
Make sure you have the latest version installed. Go to Help > Check for Updates.

You may also try to repair the installation (For Windows Only) go to Help > Repair Installation

If it doesn't work, try to print the PDF as follows and see if that helps:

Go to print > Selcet the Adobe PDF in the printer list > Print > Save the file with a new name  and check.

Let us know how it goes

Regards

Amal
