I'm a master student in Cosmology and I want to do my thesis using Einstein toolkit. The problem that I have encountered with is the error while downloading. Actually, I followed all steps which are mentioned in the download page of the website but I face an error after the step below 

./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2018_02/einsteintoolkit.th

which just says: "Could not download the file".
