When I open any of my previous BIAB song projects or an all RealTracks BIAB Style in 2010 the RealTracks only play for the first two bars and then drop out. If I reload them individually they will play correctly but after saving song and then reopening the same thing happens. I have tried switching between ASIO and MME but that doesn't help either
Anyone else have this problem
