After I bought the Unlimited version, and installed into a web hosting server, it didn't work at all . I am using Linux shared hosting server, which only allows script to run for a few minutes.

Can anyone help? many thanks.

After running crawling for a few minutes, the error is

The connection was reset
   The connection to the server was reset while the page was loading.
  The site could be temporarily unavailable or too busy. Try again in a few
    moments.
  If you are unable to load any pages, check your computer's network
    connection.
  If your computer or network is protected by a firewall or proxy, make sure
    that Firefox is permitted to access the Web.
