No, it's I've exported to PSD/PDF this way from Xara for years, never had a problem. In XDP 11, which I have, the error suddenly came up and I feared the problem, as I didn't want to move to a different application, but upon sending the file the PSD to Photoshop and it read fine, and having sent PDFx1a files to commercial printers from Xara, both no problem - but the error always shows up right before export.
