Here the real time solution.
First get the link of download from
http://vid.khattam.info
And the use "wget 'the link that you got' --continue"
"--continue" suggests that if your download is broken then it continues from the same place from where it has gone.
If the link changes then also you can easily replace the link with the original link to continue from the same place.
The wget command is a linux based command. I hope you can get that in windows and other too
