I'm using the same set up and I am having no problems. Check if you
have the latest update from Lexicon (2.12) I had some problems with
the card before I got Vegas, usually using a demo version of Cubase.
I dumped it from my system and installed the core 2 upgrade and I am
having no problems. I've been using vegas for about a month now.
When you upgrade the core drivers, make sure you follow the
directions very carefully, there are some things you have to
uninstall by going into the directories. They give a very good set
of directions on their web site. Good luck.
