Cannot use purchased license

[Sedsall]

Been using my license since 2013. Upgraded to 11 at one point. Today I open PDF and realize I am on a trial (All of a sudden my PAID software reverted to trial!!!!). I click on activation under HELP and type in my code and I get error 22 that its not the right version. I uninstall and go to my original license email and download, and of course that software page doesn't exist. 

Why would all of a sudden I have these problems after so many years of no issues! 

Please help.

Hi @Sedsall,

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

Our apologies if your Nitro Pro 11 installation went into trial mode. 
Your computer may have underwent a Windows update which causes the program to revert to trial mode.

You can reinstall Nitro Pro 11 by downloading the installer from the following location: 

32bit - http://install.nitropdf.com/professional_1108470/retail/nitro_pro11.exe
64bit - http://install.nitropdf.com/professional_1108470/retail/nitro_pro11.exe 

If you are not sure whether to download the 32bit or the 64bit, check the link below:

Once Nitro Pro 11 is installed, you should be able to activate it using your version 11 serial number.
To activate, open Nitro Pro then navigate to Help tab > About Nitro Pro > Activate. Enter your serial number then click on Activate.

I hope this helps and thanks again for reaching out. 

Kind regards,

Hi

Unfortunately this didn't work. I uninstalled my trial that was running. Downloaded and installed from the link you gave me for 64 bit, and when I enter my serial numbers (I have two emails with original and upgrade) both give me an error 22-Wrong license number. 

It looks like my email says version 9 from the last upgrade? Is this the issue?
