I've checked out the files and heres the correct answer:
files come in 2 type 16k sample & 21k sample+harmonic data
the loop points are found in the corresponding .CO file - which you will need to load manually.
To do this. locate the .co file with the same filename. click the voice to load this info into (usually the same as the voice file) then click LOAD. that will load the loop points and any other data into page 7 ;)
