HEADPHONES no sound output on cue 1 & 2 XDJ-RX2

Output in preferences in Software is only allowing 1 option. "Line (PIONEER DJ XDJ-RX2 1/2" for each channel. I have it selected for Master however, Headphones and Booth output I have left empty. The only selection option any channel offers me is like I said, "Line (PIONEER DJ XDJ-RX2 1/2". I have my audio  but no cue audio in channel 1 or 2 in headphones. It functions fine when I use it in USB mode but whe through the software control, the sound in channel 1 and 2 is lost when cueing through headphones. It is only available through Master cue and if I use USB or phono or line 1. I am using PC.Windows 7 PRO

Furthermore, I attempted to install DRIVER EXE.1020 as prompted and installation failed every time. I even tried installing it on a Windows 7 and a Windows 10 platform. Installation error message 008 and 004.I am "assuming" this is what is causing the output error in my headphone cue channel 1 and 2? Please assist
