I experience this same problem, i bought gameex quite a while ago, however i only use gamex for the karaoke function, as there is no other decent alternative for Media Center. i did have MCE 2005 and i experienced this problem when i tried to upgrade to later versions, only the version that i downloaded when i first purchased it worked, and all subsequent versions produced this error. I have sinced upgraded to Vista, and i am using the latest build of gameex. and this problem is also not working, so now the only feature i purchased gameex for cannot be used. worth noting, when i first installed gameex and tried to play a CDG file i got a message saying that the file type is not recognised and it asked me if i want to try to play the file anyway, i said yes and the sond played ok, however upon subsequent retries the songs will not play resulting in the same error above. Can you please assist me with this? the log file does not show any errors as far as the logfile displays, it says it has started the file for playback and ended without error. also just another question would it be possible to add a startup setting to load the Karaoke player directly without going to the mame frontend.
