No playback after record


Using cubase elements 8, when I record audio I cannot play it back unless I restart the current project I am on. The playback then works fine with no hassle. If I come back to an old project, I can playback initially but if I try and record anything over, the playback stops working.

It isn’t a problem to do with monitor selection, when I try and playback I deselect monitor and record.

Any ideas?

Thanks, Robert
