O have just installed GPO 4 with the Aria player and successfully registered it. Using Finale 2007 as well as Cubase 4.5.2 was no problem for the previous GPO and Jazz big band. However I get NO sound with both programs as well as when I use it as a stand alone application out of GPO4.

Can anybody help?
