I've now fixed the ZIP problem as well as for all other affected resources. The problem shouldn't occur again. Thank you for raising this to my attention.

Thanks Thalia. It seems it's a problem with the ZIP file not being generated properly if the resource title has funny symbols in it. I'm investigating. In the meantime you can download the files individually.
