But, I just tried it again on a game from my list and no luck!
Ok, manual linking again to see.
The above is for The Savage Empire, which you should have already (free and excellent game). Paste it in the address bar and see whether it's parsed correctly.
These are also the bonus items one by one, so if the game does work, check with these as well.
P.S. Are you using any addons/extensions that may interfere with link parsing?
