Sorry to hear you are having issues. I am not sure on PSD files, but on PDF files, I noticed it changed, to preview view with a small overlay on it. Which i think, it overwrite Iconpackager setting. This is what I saw on my system.
Anyway, I have forward your problem/question to Stardock Support Team for their assistance. Please keep an eye on this thread for any updates. We appreciate your feedback and patience.
