If you upgrade from EmotivBCI before v3.6.5, you should notice that we change the format of training profiles so that the existing training profile (i.e. created before v3.6.5) will not be fully supported. We call them readonly profiles which can only run at a live mode and cannot run on training mode.
These readonly training profiles only support headsets with 14 EEG channels (i.e. EPOC X and Flex with EPOC X config mapping).
