We are using 2.6 to record Church Service. We are recording on the same computer being used to run the Projection System for Church. Many times lately when we Export to WAV, we get "Nothing to Render". I have gone back through the files saved & sometimes there is a good recording & other weeks a small file with nothing in it. When I test for a minute or so, I always get a good file. Does the program just 'stop & dump' after running 'too long'? Sometimes we record an hour & sometimes 1 1/2 hours (recording just 1 track).
