After upgrading from Nitro Reader 3 and Win 7 to Nitro Reader 5 and Win 10, I can't add my signature to PDFs without a password. This is a good security measure, but as it's a new addition, I never used a password for this before and think I do not have one. The support forum requires I log in, before asking questions, but I don't have a password there either and when I ask to reset it it tells me I cannot do so.

Anyone know how to get a password from them? There seems to be no "Contact Us" on their website.
