Outlook Express is unable to download the list of newgroups

Hi,
I am trying to retrieve newsgroup list from server function but it shows empty file. After some time the message is given that, the list is retrieved, but there is nothing to show. I tried many times to get this list with different ways but I need the expert advice. Can you give me any suggestion to fix this problem?
Thanks in advance.

Error Message: Unable to download the list of newgroups. An error has occurred.
