Topic: Problem with Fireface UFX and Logic 9

Hi,

I have the new Fireface UFX running with Logic 9 Pro on Leopard and Logic is crashing. Well it is not exactly crashing in one point all audio simply stops. Should, I update to Snow Leopard, what is the problem?
Please help. I updated the driver to 2.9. It runs fine with Ableton and I recorded a few sessions in Logic and it worked. But now something is happening.
