OK, I’ll try again…
In the screenshot that you gave us, and as @Scab_Pickens previously suggested, there is NOTHING to export, simply because your Audio 01 track is empty…
What would be useful is to know, first, to where your MIDI 01 track is routed (Output routing drop down list in the inspector) and, second, what you try to get recorded in the Audio 01 one, because, set as shown, you’ll never get an audio from any VSTi, as it seems directly set to record a hardware input, NOT a VST instrument.
Additionaly, if your audio source is a VSTi as it seems the case, it would be better to use an instrument track (this one has an audio output that will be directly audible in the resulting file of your audio mixdown), unless you have a good reason to not use one (in example, a multi-outputs VSTi…).
EDIT : I have looked at what the IcarusX64 instrument seems related to here : there is nothing related to any multi-outputs feature. So, the use of an instrument track is obviously better , in this case…
