LinuxCNC 2.8 doesn't run after upgrading from 2.7

Hope someone can help me debug my installation. I was running LinuxCnc 2.7 then upgraded to 2.8, now I can't get LinuxCnc up and running with my machine configuration (it runs until I try to load in my machine config file). I'm running Debian Stretch with RTAI. See attached error log file:

OK, I have installed Debian 10 with LinuxCnC 2.8.1 from the LinuxCnc 2.8.0 - Buster installation image. I am now running the RT-Preempt kernel. uname -r gives "4.19.0-13-rt-amd64" and I am using uspace LinuxCnC. I think this is correct from what I read in the "getting Started V2.8.1" Manual.

My machine seems to be running OK now.

THanks.
