See another guy had this problem too.
Im new to AMD GE , Plays and raptr stuff.
But when had the guest temporary account I first was sign up to. The hud showed. After i creat new personal account it dont show anymore.
Dont know if that maybe give you some more info ro find the root of the problem.
The only way I can see this issue arising where it would work from a guest account and no longer work from a permanent account might be in the Preferences.
Make sure under Preferences > Games to have "Tracl game play statistics" enabled.
Also, when selecting a game in your Game Library, make sure that "Track gameplay" and "In-game Overlay" are enabled.
