sorry I lost you at ASIO2ALL.
why would you be using that when your device has drivers for win 7 x64 right on the site. ?
you have j bridge?
sonar uses bit bridge. is that what your refereeing to ?
and if you think your smooth with that using 32 bit plug ins, think again.
the reason I mentioned it wasn't for my health, I was trying to help you.
there are some plug ins that will crash you out on a 64 bit system if its a 32 bit plug in.
I happen to know of 4 off hand.
but if you've traced it down to windows update and asio4all then your all set.
good luck.
