I recently updated my version of NOD from 2.50.45 to version 2.51.20. No problems with the install or the like. I did notice though, that it won't update without manually choosing a update server for it. I have it setup to update automatically, like everyone else here I believe, and to choose a server automatically.. But I noticed it stayed with the same virus signiture that it had from the day I updated the software, when I would click update now, it would say my version was up to date. Came on the forums, noticed an update for today, went back, click the update now button, same thing, I get told my version is up to date. I then manually choose server: u3.eset.com, click update now, and I get the update for today, so what gives? Is this a bug or something?
