Well I’m new here also, so given the information you’ve provided, I’m only guessing at the issue. Forgive me for asking, but let’s first get the basics of the situation understood.
Question #1: Have you successfully unzipped the .zip or .rar files? If not, download a tool like WinRAR (I prefer 7zip) and unzip these files first. Usually there is a rb3con file within the compressed file. Do the extraction first before using Party Buffalo to inject them into the flash drive.
Question #2: if the files are already unzipped, can you provide a screen capture of the files and any error messages you are getting? A picture says a thousand words.
