I suppose you could blame this on my system/drivers, but when Audition 1.5 fires up and works every time, and Audition 2.0 will freeze my machine after closing it, I guess I tend to go with 1.5.So it may work fine for you. I have several audio interfaces, and a TON of VST's, which are probably part of Audition's problem.The audio hardware configuration is confusing in Audition 2.0 and seems a little flaky, for instance, 2.0 won't recognize my Samson CO1U USB mic although 1.5 did. The hardware configuration UI in 1.5 is more like the hardware config UI in Sonar and Reason and Live.
