This is getting crazy. Just uninstalled AS beta 1.4.9.7 and re-installed. Logged into AP through the AnyStream AP tab, switched to Voyager Season 3 and it worked! 26 Episodes in the tab *and* downloads, so I downloaded S3E26. Yay! Switched to Season 4 and the same problem again, tab E26, downloads E25. Returned to Season 3 and suddenly there as well: tab E26, downloads E25. Logged out and back in again, without even closing Anystream, and I'm currently downloading S4E26. So it wasn't even necessary to un-/re-install, just to log out and back in. I've downloaded quite a few shows in the past with AnyStream but this kind of thing never happened before. At least this confirms to never give up.
