Nitro Pro 11 crashes when signing a document

Now when I initiate a sign operation on a document, Nitro Pro 11 immediately crashes.  I downloaded the latest version, 11.0.8.470 and it still crashes.  Can someone help me

Hello @Scott Perry,

Thank you for reaching out to us through our Community Forums!

In order for me to further assist you with your concern, could you please send me a private message and provide the following?:
-The serial number of your Nitro Pro. You can find these out by clicking on 'About Nitro Pro' under the Help tab
-Does this happen with every file? If it's a single file, please send us the sample file (with sensitive information extracted) so I can replicate it on my end
-Support Tools file from the affected machine. Note that if the tool is not found in Help tab, you will need to go to the installation folder of Nitro Pro and open NitroPDFSupportTools.exe: http://kb.gonitro.com/knowledgebase#/search/support tools/000001594

Thank you very much in advance and I am looking forward to hearing back from you.
