I am using MSG Data Mager Version 184.108.40.2065 (newest beta)
Data is received on data channel E1B-TPG-1
A Entry for this channel is required in cast-client-channels_bas.ini
Be sure to select a target directory that is scanned by MSG Data Manager.
EUMETSAT_Data_Channel_4 is a good choice.
Then check the GOMS Channels in Setup->Channel Selction->FSD
