You mean the initial question when you start PSI?"Do you want to refresh the list?
If the hp package is not listed, then you must confirm to refresh the list.
I run a serverside script maybe once a month to get the current list of Barrys packages in PSI.
I just updated it yesterday.
To see the latest packages, you must confirm to refresh the list.
PSI offers this question, because all those lists are quite huge, and might take some minutes to download on a dialup-connection (with ADSL it takes only some seconds).
