Hi, Alan.
Bob told you how to get the update. I'll try to tell you how to get back your deleted messages. I said "try" because you are using Forte Agent - which I know nothing about.
I use Windows Live Mail. In WLM, we can click Tools | Options | Read. On that tab, there is a News section, which has a box for "Get ___ headers at a time". The number in the blank is 300, by default, but it can be increased to as much as 1000. Or, we can remove the check from the box and get ALL the headers available on all news servers for all newsgroups. (This can take a LONG time, even with broadband, for an active NG like this one!) WLM also has "Synchronization settings" for each subscribed newsgroup; we can choose to get All messages, New messages only, or Headers only.
My Quicken NG currently shows over 50,000 messages going all the way back to
2003. You probably wouldn't want all those. But, if you were using WLM, you could set Sync to All messages, and the number to 300; that should get you the 300 latest messages here - which probably would include the recent update discussion that interests you.
Agent probably works differently, but it might have a similar function.
