No Save-As dialog box



I purchased pdfcreator v9.6 off ebay, but although it seemed to install correctly, it would show PDFCreator as one of my printers, but when I selected it to print, it doesn't bring up anything, nothing to save it to, and I can't find it anywhere if it has autosaved.

I went to the website and downloaded v9.9.  I uninstalled c9.6 and reinstalled v9.9 but the sme problem happens.

I am using windows7.  Can anyone help?
