The HippoPlayer.group must match the HippoPlayer executable ("HiP"), meaning it must be taken from the same archive/package/distribution as the executable.
HippoPlayer first looks for HippoPlayer.group file in the executable's directory ("PROGDIR:").
Then it looks for the file in the location given in HippoPlayer's settings (preferences).
If HippoPlayer reports an error with the HippoPlayer.group file, there's either a wrong one in PROGDIR:, or HippoPlayer's settings point to a non-existent, or wrong HippoPlayer.group file elsewhere.
Simplest solution is to just put the correct HippoPlayer.group file into PROGDIR:, and delete HippoPlayer.group files elsewhere.
