Grabit is the software, the other key is what newsgroup provider/server you are using. They differ in retention (how long they save articles), and that's most likely what's causing your 'article not found' message. This guide ( http://www.slyck.com/Newsgroups_Guide ) has information on different providers. The few ISPs which still have newgroups generally have limited retentions (1 month to 100 days) some of the pay services have close to two years. Some providers has a free trial period, so if you are only after a few discs, that could be something to try. Then if their service agrees with you then you get a full subscription.

Thank you none. I'll try Newsdemon's trial version, since I'm European.
