Pato's bearing mod problem

[Crécy]

I replaced all the submarine files with the Pato's bearing mod and it still does not work. Apparently I also managed to destroy my career in passing when trying to get this mod working. I downloaded my career to see the nav map if the mod was installed properly and when I quitted I got error from SH3 Commander 'Invalid argument to data encode'. This mod is pretty vital since I'm mainly using dead stop plotting.
