CS5.5 Trouble with Zoom R16/24 and ASA4LL drivers

Hi,

I know this is an old AA version but it does what I need it to so haven't bothered to buy a newer version.

Actually used the original programs before Adobe bought it.,

I have a zoom 16 interface which I use via USB with the latest correct drivers and most times it is fine and it all works.

Every now and then, when I start AA or open a new file, I get a panel saying there has been a change and then the ASA4ALL driver automatically inserts itself.

It takes forever to get the Zoom driver back so I can record again.

I use the zoom driver with ASA not MME and when it works it is great.

How can I stop it automatically bringing in the ASA4ALL driver please?

Thanks
