Firmware sx2

I just got a new sx2. It's my first piece of pioneer equipment. I'm use vdj8 and want to connect my two tt's to the sx2. I downloaded the drivers fine. When I tried to download the firmware I realized I had to install java. I did so. I followed the instructions. I downloaded the firmware I clicked on the download to unzip the files . When I click extract all it ask me where to send the files. The location seemed a bit strange but clicked ok. The located the extracted file and double clicked java tries to open the file but then gives me an error and says have could not open the file.
