Difficulty in activating license

I was experiencing some glitches within the use of Nitro Pro PDF. I uninstalled the program and then tried to reactivate my license.  The response when activating license is to select a license to deactivate however there is not a number to select.  I am temporarily using a trial offer until this is fixed. Please advise. 

Serial Number 504958-uvwxyz-586819
Version 13
Status Active
Number of Activations 0
Number of Activations Allowed 2

Hello @Cathy Marshall,

Thank you for reaching out to us through our Community Forums and our sincere apologies for the delay.

For your information, our Activation Portal is only used to deactivate previous activations. If there is nothing to release, all we need to do is to proceed with the installation and activation.

To assist you, please reinstall using these direct MSI installers:

x64   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x64.msi 
x32   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x86.msi

To know if you have a 32-bit or 64-bit Windows system, please refer to this article:

Important: If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. 

To bypass this, please try these steps:

a. Right-click the link you're trying to download and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"


After installation, you can activate it by opening Nitro PDF Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 504958-uvxwyz-586819.

Thank you for choosing Nitro and I hope this helps.
