Ventrilo, Games, and Vista

Hi there,I just recently upgraded to vista. Everything worked fine prior vista, on XP SP2. I use ventrilo while playing Lineage 2.Once Configuring Vent and Lineage 2 to run in XP mode, SP2 mode, vent works fine & so does the game...as long as I don't run them together. See below:Vent on & game NOT on = Vent works fine Game on & vent NOT on = Lineage 2 works fine Game on & vent on = Game lags extremely bad, and vent freezes. (this may only happen once I push my PTT button...not sure yet)My details: Creative Sound Blaster SE (Vista 32 drivers) Game = Lineage 2PLEASE HELP
