Problems with Onyx 400F and Audition 2.0 (Clicks)

Seems like I am having ASIO problems while Using the (ASIO Onyx F Series ) in Audition 2.0 :

1- There is a Click almost every time I press the Play/Stop button , in Edit or Multi track View.

2-When I load a session , some times it does not play!, When I press the Play button , the cursor freezes and doesn't move ! , do for losing connection with th 400F, and the inputs-outputs changes in each track to notinng ! then I have to choose the I/O in the track again .

3-When I play a session with Real-time effects , that meens Clicks Clicks and Clicks , eaven thogh i am using only two effects or less in a one track project ! in 512 buffer size .

while with Audition 1.5 i have a project with more then 40 track , each track have Real-time effects like reverb,delay,and more , i can play all the sesion without hearing a single click.


And you guys with other Recording interfaces , do you have similar problems ?
