cannot export arrangement to audio file

Gday there,

I’ve tried a thousand times with a miriad of different combinations but to no avail…

I’ve completed an arrangement and want to export to wav or mp3, whatever.

It exports a file but with no waveform, just a flatline with no sound.

I’m 100% that i’ve ticked the correct boxes and have the correct file paths.

I’ve exported hundreds of songs but this one wont comply.

I’m using Cubase 5…fully paid too.

Regards from Jase.
