I found a solution to this problem that works for me. The download kept looping while trying to download a file and would restart to download that file. I found this:
This worked for me. When I went to the location he specifies I found lots of folders and, at the end, one file that was not a folder. I deleted that file and restarted the download from where it had got to. It has not looped again and I have over 50Gb downloaded.
The file that mine was looping on was fs-base-0.1.61.fspackage.002
The file I found that I deleted was fs-base-0.1.61.fspackage.001.
I guess that the original download of the 001 file had not completed properly but the installer thought it had and tried to download the next file (002) and became confused.
Hope this helps.
