Help needed asap with updater please

Hi,
Comodo released an update few days ago and I started the update today after the update went upto 15% my connection was lost and came back within a min. It has been 15 min now and I am still waiting for it to move from 15%,it is still at 15%. What shall I donow?(I thought that if the connection is back the updater must resume the updating.)
Thank you in advance.
Here’s a screenshot.

UPDATE:
Hi guys,
Just now I right clicked that green updater icon in the system tray and clicked abort and cancelled the update. Now do I need to remove the installed files to do a update again???
Please let me know.
Thank you in advance.

Update:
Hi guys,
Just now I tried to update it again and the update was a success I think.
Now I just wanna know what happens to the files that were downloaded during the failed update and what shall I do with them?
Please let me know.
Thank you.
