Quote: It seems that "MESS_progetto-SNAPS.xml" expects "pS_MESS_Snaps_20150710_(cm).zip" to contain pS_MESS_Snaps_20150710_(cm).dat". It actually contains "pS_MESS_Snap_20150710_(cm).dat". I'm not sure which is correct. The DATs page points to "pS_MESS_Snaps_20150711_(cm).zip", but that one is not available for download.
