I had Sibelius 4.whatever + Kontakt Gold + GPO all working just fine. Then, when Sib5 came out, I bought it, and GPO (at the very least) is no longer functioning. (If I try to use it, I get tons of "File was not found. Please check if Library is installed correctly" errors when I try to play a piece.)
Same happens with Sib. Gold & Gold eco. under Play => Playback Devices => Active Devices => KontaktPlayer2.
Sibelius Essentials plays fine.
Nothing else in my system has changed in months. Running XP Media vers. on a Dell XPS DXP051, dual P 2.80GHz, 350 GB RAM + 12 GB virtual RAM.
Have tried uninstalling Kontakt & GPO and reinatalling them. Get no error messages during install. Have tried rebooting after installing, also, "just to make sure" (though it doesn't ask to). Still get same "File was not found" errors if I choose any Kontakt playback device other than Sibelius Essentials.
Have not seem anything anywhere saying GPO needs an update to run with Sib. 5, so hope I am either mistaken or you can otherwise point me in the correct directions.
Thanks in advance for all your help in this matter.
