I use Pro Series basic and do not have any trouble saving PDF files my system is standalone, I can't even follow the scenario you were describing. When you select print from the left hand side of the screen then you have 3 tabs at the top, file copy, client copy , preparer copy, and then print options. Check that your print options are what you want and that you have selected Pro PDF as the default location when you installed the software then select preparer  tab and click save as a PDF bottom of the screen if your system does not look like that maybe it's not basic.
