Can't add templates, layers, or resize imported images

Hi, I've just bought FMKE, but when I open it up, I can view the templates drop down menu, but no preview shows up, and when I try to open it, I get an error message. I am also unable to add a new layer manually on a new design, as nothing appears, and when I import an image I get an error message if I try to resize or crop the image. Am I doing something wrong? I've uninstalled and reinstalled, and checked for updates.
