Don't be sorry! I want it to work for you :) Are you on version 1.1.1 ? You can find out on the title screen what version you are on. You probably have to re-download the file here on itch. Your saves should be intact still after redownloading.
Yes it is i was able to get the Allister to work and grey but kai route is still stick at the same part it I'll try to restart it and see what happens maybe I did something on my end lol
