When you say you’re downloading the data, are you using the “custom download” tool? If so perhaps you’re running into the same problem as reported in Custom downloads ?
I mention a workaround there until we deploy the new release which includes the fix.
However, if you’re experiencing a different problem, please let us know a little more information. (Are you downloading the data via the “Custom download” tab? Or a download link on some page?)
Thanks,
Phil
