Why doesn't CreatePDF Desktop Printer work with Win 8.1?

I purchased this software because I need to convert Microsoft Office documents into PDF for my job. I did not see any prompt informing me that the program was incompatible with my Windows 8.1 OS until after the download was complete and installation began. When I attempt to print to PDF using the Adobe program, it appears to be the process then nothing else happens. No file created to save, no prompts, no error message, nothing! I need to get a refund or have the finds I used to purchase this program applied to the purchase of a PDF Creator program that works with 8.1.
