Activation and installing Nitro 13

[Myra Bresnahan]

I changed computers and installed Nitro 14, not realizing I bought an older version.  !4 does not recognize my license number. I uninstalled and tried to install 13 several times, but every time after installation  the program will not open and it crashes.  I am in hour 4 now, trying to activate my Nitro.  This has been a long and frustrating process which includes a multitude of other problems that I encountered, but have since resolved. I need Nitro for my work. Please help ASAP

I do apologize if you are experiencing an issue installing and activating Nitro PDF Pro. 

I would like to check first the version and status of your serial number. Kindly provide it so we can determine the correct installer to install Nitro PDF Pro. 
It will be okay to send the serial number here since we always hide it before approving the post.
