Hi guys,

I am trying to download this website

<https://www.ncbi.nlm.nih.gov/pubmed/>

But everytime I try I have this error message:

**Mirror Error!**
HTTrack has detected that the current mirror is empty. If it was an update,
the previous mirror has been restored.
Reason: The first page(s) either could not be found, or a connection problem
occured.
=>Ensure that the website still exists, and/or check your proxy settings!<=

I have to say it is the first time I am using this program. I tried another
site and it worked. Can someone help me? Do I need to change some settings?
Can someone give me the reason why it is not working?
Thanks,
