I have updated to 3.0.1 but am still getting hangs and runtime errors. The last Run time error was R6025 - pure virtual function call, happens when I go to select an audio source. Running Reason in slave mode frequently causes hangs.
I run Vista Ultimate x64 SP1 on an Hp 8400 with two dual Xeon 8 gig Ram and 4 TB of HD. I use a Motu 828 Mk 3 sound card and an Nvidia Quadro FX1500.
