Error message:  "Creation of this signature could not be completed.

This error can occur if your (self-signed) digital certificate has expired.
By default the plug-in creates a self-signed certificate with 1-year validity the first time you use it.
Provided that the "Create Certificate" option in the installer is enabled (see screenshot in number 6 below) then it should auto-renew.

Alternatively you can manually generate a new self-signed certificate from the Details Dialog by selecting "New ID" which is the bottom entry in the Certificate drop-down:

You will then be prompted to enter your details for the certicate and you can select a validity period of up to 5 years.

Regardless of you how generate a new certificate, make sure that you select it from the dialog box which appears when signing:

If the dialog box does not appear on your system then it can be enabled as follows:

1. Go to the list of Programs in Control Panel (may be called Apps and Features)

2. Select the entry for "sign pro plug-in for Adobe Acrobat"

3. Click the "Modify" button:
   

4. On the "Welcome" screen click "Next":
   

5. On the next screen select "Change":

   

6. On the options screen click the checkbox for "Show details dialog":

   

7. Reboot your PC

8. The next time you sign a PDF using the plug-in the "Details dialog" should be displayed and you can select your desired certificate
