Quite relevant with the advent of importance sampling in LW2015.
Hi Chris, thanks for coming back to me concerning the 'corrupted' zip file problem.
In the meantime I got the 'The Unarchive' app from the MAS which solved the problem I had while trying to extract the bundle. Perhaps Apple should update their internal ZIP routines to avoid such kind of trouble.
Everything fine now ... no further actions required.
Looking forward to feature the probes in some future renders.
