Unfortunately, AINDecompiler was last updated in 2015 to account for Evenicle, and later games aren't necessarily compatible. Specifically, Heartful Maman is AIN version 8, but the decompiler only supports up to 6, with rudimentary this and that for 7. It would take some possibly significant programming work to update the program, it's impossible to say at a glance.
