In your first post you said it looks like you will have to convert your PDF files to PES, there is no way you can do that. No matter what software you use you can only convert embroidery files like PES, DST, JEF etc., to other embroidery files, example convert DST files into PES files. You cannot convert a PDF, JPEG, TIF, to an embroidery file. When you tried to install the trial version of Embird did you download it and then install it? As with most software, it is downloaded onto your computer and then you have to install the downloaded file. It's possible you downloaded the file and it's sitting in a temporary location on your computers hard drive. You will have to install it in order for it to work.
