Hi jozefc2016 ,
Would like to inform that it seems that certificate is causing this behavior at your end.
Please recreate the certificate & check for the same.
Also is this happening on other system as well?
thanks for your prompt response. It is hard to believe that the source of the problem is the certificate: the issue is the same on both of my computers, but as mentioned in my original post the same certificate still works with MS Outlook - I can digitally sign e-mails. Moreover, I can access the dongle containing the certificate through its maintenance software (Nexus Personal) and I can see the trace-ability of the certificate until the root certificate and I can change the PIN for using the certificate. Finally, today I was able to insert a digital signature using this dongle into an MS Word document successfully. If you could provide me your e-mail address I could send you a digitally signed e-mail, so that you can see the certificate itself as a proof that it is OK.
My only logical conclusion is that it is indeed Adobe Acrobat, which stopped working with the certificate as it used to work until a week ago...
I too am having a similar problem. When I try to complete a AAR form, the software locks up my PC after filling in the first blank. The only option after this is to reboot my PC. I thought the issue may be with the new DC version so I uninstalled it and went back to version XI which has the same issue.
For testing purposes, you may try to rename Security folder at: C:\Users\user name \AppData\Roaming\Adobe\Acrobat\product version (Dc or 2015) . Make sure Acrobat/Reader is closed
Don't delete the folder that will lead to the removal of your old digital id. Launch Acrobat and try to recreate your id or sign the document again. Check if the issue occurs.
If the issue still persists, you may delete the newly created security folder and rename the old one back to security.
When was the last time it was working fine?
thanks for your suggestion. I tried to rename the folder and then sign a document - unfortunately the result is the same; Acrobat hangs again. Acrobat found my certificate on the USB dongle immediately, but while saving the signed document it crashed as before and the saved document has an invalid certificate.
As you suggested, I deleted the newly created Security folder and renamed the original one.
Searching through my files I found that the oldest successfully signed document was made on May 9, 2016. After that I was out of office for some 10 days and since my return I am having this issue.

After several suggestions made by Tariq (thanks for all the efforts) I am still unable to use Adobe Acrobat DC for signing my documents with the external dongle containing the certificate. For now, I uninstalled DC and installed the older Adobe Acrobat Reader Ver. 11 - which works perfectly with my certificate as it used to work before.
Obviously, there is some unidentified conflict between the latest update to Adobe Acrobat DC Ver. 15 and possibly some Win10 updates, which made the use of the certificate impossible.
I am not sure how much I am loosing from the functionality of the reader by reverting to Ver. 11, but at lest I got back the ability to digitally sign my documents, which is an essential feature for me. Until a completely new version 16 is released, I will not attempt to do any upgrades - after that I will give it a try, but store the installation file of the good old Ver. 11 at hand for downgrade just in case...
This seemed to work for me.
Go to C:\Program Files (x86)\Adobe\Reader 11.0\Reader
Right click the AcroRd32.exe and select Properties
Select the Compatibility Tab
Check the box that says Run this program in compatibility mode for:
Choose Windows 7 from the drop down
Select Change settings for all users if applicable
Select OK to exit
Adobe reader should now launch normally without error.
Hope this helps someone else. Cheers.
as stated above, Ver. 11 works fine for me, even if I am not running it in compatibility mode... My issues are related to the newer versions of Adobe Reader. I did not try any recent versions, since I do not want to lose time by experimenting anymore. Thanks anyway, Jozef.
