Spectral Layers 7 bounce to Wavelab

When I try to bounce a selection from Spectral Layers Pro 7 to Wave Lab Pro 10 I get an error regardless if I am doing it inside cubase or starting standalone

Any ideas?

This dialog happens after WaveLab was launched by SpectraLayers with your audio segment, and it tells you that SpectraLayers is now waiting for WaveLab to modify the file.
When you’re done editing in WaveLab, save your file, and SpectraLayers should then detect that the file was modified and ask you if you want to import back that modification.

Thanks !
