Klipper Error after 2.0 update using old cfg from 1.1

Hello. I am in the process of putting a new octopus 1.1 board in my machine and though I might as well do the RatOS update at the same time.

I fallowed the initial configuration process which is nice and easy now but when I but into RatOS I am now getting this error. See attached screen shot.
I know there must be something wrong with my old config file. Includes path needs to be updated or something. Trouble is I have not been able to find it in the config file.
