Norton Identity Protection Extension causing Nitro PDF Plugin to crash in Chrome

Hi,

 

I recently noticed that when I  used the Nitro PDF in Chrome, the plugin would crash when viewing any PDF.

 

Disabling all my extensions and then re-enabling, I found that disabling Norton Identity Protection would enable me to view PDFs with the Nitro plugin.

 

I don't know if it's related but I recently used Norton RnR to to do a reinstall of NIS 2012 to get my Firefox add-ons working after a fresh install of Firefox.

 

I don't want to disable the Norton extension so any help would be appreciated. I'm using Nis 2012 on Windows 7 x64 Home Premium.
