I suggest trying again. You may have picked a bad moment, while the download site was updating itself.
Otherwise, it might help to go into advanced mode and pick a smaller scheme, such as 'basic scheme'. You can always add the full scheme later.
There is also a command-line option -select-repository which provides a drop-down menu of available mirrors. Some mirrors might have a better connection than others.
