Sorry for the delay. There were still a few issues to track down. I have completely wiped out my profiles, dats and downloads to start from scratch.
The first issue that I notice is that "pS_AllProjectMESS_20150815_(cm).zip" as specified in "MESS_progetto-SNAPS.zip" does not exist to download. The newest file that I found on the server was "www.progettosnaps.net/dats/cmdats/pS_AllProjectMESS_20150813_(cm).zip".
