Problem downloading El Capitan!

Hello,

During the downloading process (the 1st gb) of OS X El Capitan, the wifi signal got disconnected (router issue), so the download got interrupted. I could not resume the download later, I deleted the file in the application folder (though the 'Launchpad' still showing its icon!) and tried to restart the download process, but still nothing. All I get is a request to enter my iCloud password, then when I hit 'resume' I get a waiting message and that's it. I hope these 2 pics can clarify what I meant.

If anyone could help with this issue it will be much appreciated.
