purchased upgrade, but "Specifies that we were unable to complete the activation of the product."

I own a pdfpen for Mac v.12.  I purchased an upgrade to Nitro PDF 13 pro.  But when I try to activate the software, it said " Specifies that we were unable to complete the activation of the product."   I don't know why ?

Hello @Leo Kwan

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

I tested the new key.  A new error message shown up.  It reads " Unable to obtain license.  Please try again in a few minutes."   I did try a few times, but the error message show up every time.

(Earlier, when using the old key, the error message is " Specifies that we were unable to complete the activation of the product.")

Hello Leo,

Sorry to hear that!

Please try the whole process again using the same voucher code.

Kindly let me know how that goes.
