BitComet was downloading and OS crashed

As BitComet was downloading a worst crash happened that caused OS failure and then was reinstalled.

The BC and the downloaded is installed in other place than the OS so there's the .blc file and .torrent file intact there.

So how can I resume it to have BC downloading it as normally as it was before disaster while If the BC launched it has no the DLed item in its DL list anymore?

THANKS MUCH before

If you can access the hidden folder in /appdata/Roaming/Bitcomet, copy that to a thumb drive, re-install the OS and just copy it back to the same location.

To get at hidden fiiles/folders, open the drive, go to 'view' and 'options'
