How to re-download all headers from a subscribed newsgroup?

[kheldar01]

Hi

I have recently bought a subscription to another usenet service that should have a better retention of my ISP newsserver so i added the server to the list of servers in newspro.
Then I tested it on a group I already had subscribed and used before.
But when I used rescan headers I got only few new headers with today's date, while I was expecting a lot of old articles.
How can I get again all the headers from past days too?

Other settings i'm using are:
50000 articles per group
from 1-30 days
the rest retain
purge deleted headers no.

What I would is a complete list of all articles available (in the last 30 days) on the new server I just added even if I already downloaded some of those before with my other server.
Maybe 50000 is a limit too low?
I tried reset newsgroup command too and then rescan headers. Only few headers showed.
Problem could be on server ?

thanks in avance

in case you deleted headers previously

if purging deleted is disabled (edit menu) invoke edit menu->show deleted headers; select headers you want to undelete and invoke 'undelete headers' from the context menu.

if purgine is enabled, disable it first, then invoke rescan headers and afterwards apply the said above.
