Sudden stop of download

I have been facing a problem recently so i decided to uninstall the old version of bitcomet n install bitcomet 1.26.

The problem is that when i leave my laptop to download like overnight or for a long time, i come back to find a red X mark and the download has done 1 or 2% only… What is the problem and how to prevent it…

thanks in advance

The red X shows when there’s no enough space to in the download destination.

Your HDD might be full.

The red X used to mean that BitComet could not write to the disk. That could be for any of the many reasons that a program can’t write to a disk, only one of which is that the disk is full.

This was most commonly caused by a permission problem, or an invalid pathname (like, illegal characters in a filename), for example.

The meaning’s been expanded several versions ago, to include any fatal error, and you can mouseover the X to see what the exact problem is.
