Can not activate Nitro Pro 12

Hello - for some reason my Nitro Pro 12 was not working and it asked me to purchase a subscription or activate my subscription.  I tried to re-activate my subscription using my Serial Number.  As instructed, I first de-activated my subscription (although it was showing that it was not activated) and I uninstalled the program, re-installed it and then tried to activate my subscription.  It gave me Error 24.  I checked my license and it showed NO active licenses but 2 unactive licenses.  How do I rectify this issue?

Hello @Camille Seabourn,

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

We want to make you aware of the change to your product that may affect its activation performance and to continue offering our customers the very best PDF tools, we have upgraded our servers so please use our offline English MSI packages:

x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi
x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi 

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

After installation, you can activate it by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 234601-xxyyzz-319669

Thank you for choosing Nitro and I hope this helps.
