No mind readers here. There's no way we could possibly know since you don't
bother to give ANY information.
Look in the log file, the last few lines may point to the problem. Always post
the actual command line used (log file line two or doit.log)
The slow download my be because you overloaded the site. Try reducing to one
connection/sec.
