Aperture 3.4.1 issues - incl. doesn't work with Topaz
I have recently returned from holiday and auto-updated Aperture to 3.4.1.
There were some minor problems. My plug-ins all wanted their serial numbers entered, but that was easy.
However, I also use Topaz labs software as an external editor (and also a plug-in). The program is called photoFXlab. Although I have set it up in Preferences -> Export and pointed Aperture to the program, when I try to use it the photograph I am working with doesn't come across to photoFXlab.
Under Preferences -> Export I have set the file format to be TIFF (16 bit) at 300 dpi, but it appears that Aperture is not creating this file.
I'd be grateful for suggestions on how to fix this.
Thanks!
