Suddenly, the project can't get anything form the website and the download
speed keep 0k/s more than 2 hours, so I cancel the processing project.

If I close the software and restart it again, how to do can let httrack start
the project and try to continue to download.

I try to load the project and select "continue interrupted download" and
select next step, the project can't continue to process the project
successfully.
