Pro Tools 12 not reading ilok license correctly

[Inglesworth]

Specs:
Mac Pro 5,1 (Mid 2012)
3.2 GHz Quad Core Intel Xeon
32GB RAM
Mac OS Sierra 10.12.6

Yesterday I upgraded this system from Yosemite to Sierra. It was running OS 10.1.5 and PT 12.1.

My ilok license is the "Pro Tools Perpetual Bundle (with 10/11/12)" Upon upgrading to Sierra 10.12.6, I went to the avid account and downloaded the installer for PT 12.8.3.

When i try to open pro tools, I receive an error message that says:
"You are trying to run a newer version of Pro Tools than allowed by your license. You can uninstall this version of Pro Tools and reinstall any version of Pro Tools that is supported by your license, or visit your MyAvid account to renew your upgrade plan."

I can't figure out why this is. My ilok has a license for Pro Tools 12 on it, and I am trying to run a version of Pro Tools 12.

Anyone have any ideas?
