Hey, thanks a lot for your reply! I downloaded that monitoring program and I get the message - “your system appears to be suitable to run real-time audio without dropouts”. Can I ask what Firewire card you’re using now? I’ve been thinking about upgrading to a more stable audio interface, but don’t have the cash for that at the moment, and would like to just try to fix this first. I might even downgrade to Win 7 just to get it back working.
