Barefoot_Monkey: Currently that is the latest version. It does its job well and I like it, but it could stand to have a few improvements (some kind of message when it fails to log on, type-insensitive email address - little things like that).
When you right-click on the System Tray icon and click Check For Updates, do you also come to a blank page (except for the GOG.com navigation bar and copyright info)?
Free Download Manager seems to work a lot better for me than the GOG Downloader. I don't know why. I think it has something to do with my satellite internet connection and long ping times causing multiple timeouts across the board. I hope that the new "Gen4" upgrades my ISP is implementing this quarter will fix some of that.
