That's a very good question. I decided to try PT9 on my clean Win 7 laptop as my main machine is still XP. Install went fine but PT force closes at the end of it's plugin check (that's a rather annoying place in the startup for it to decide not to work) saying it can't find an interface, despite having a working ASIO interface (tested using other apps) plugged in via USB.

I installed my M-P interface in the vain hope that it would work with a known working m-audio interface and hopefully let me change over to my ASIO interface in setup but no joy.

Unless this is a bug thing, my next idea is that maybe I needed to have PT8MP on the machine and downloaded the upgrade installer?

I can't find a list of known working ASIO interfaces although I believe one must exist somewhere.

At the moment, I have an expensive file taking up space on my HD which is rather frustrating.
