Hello, when I try and download SampleData, I get this error:

Is this a new problem? Could you try a Slicer version from two weeks and one month ago?  
You can download older versions by specifying `offset` or `date` argument on the download page (see [here](https://www.slicer.org/wiki/Documentation/Nightly/FAQ/General#Where_can_I_download_Slicer.3F)).

Yes, it had been working for the last week. This is version 4.11(the preview I think). I’ll try again then.
