Cubase 5 & Focusrite Sapphire 6 Audio issue

Hi there I am running the latest version of Cubase 5 & use a focusrite sapphire 6 running off a PC. I am having audio issues that focusrite seem unable to help me with? In the middle of a project my audio just stops playing & being monitored by cubase. Cubase continues normally however with the absence of audio display or sound. If I restart cubase the audio comes back until the issue happens again (I do not have to restart my computer)

Any one else encountered this & found a solution? Its making me real sad :cry:


Please read this topic and some of the solutions presented. I think there will be something here that will help.
