Can´t record multiple channels U-PHORIA UMC404HD

So I recently got this Behringer interface. It works pretty well, but I can´t seem to record mure than 2 channels at a tiem. How can I solve this?

I´m using Windows 7

See this topic:

Audacity’s (free) competitor OCENaudio can record more than 2 channels …

apparently OCENaudio can record 8 channels.png
OCENaudio does not have the editing tools Audacity has,
but you could save the multi-track recording from OCENaudio
and open it in Audacity to edit it.

So can Audacity if the device drivers support multiple channels.

Yeah, I tried the solutions given on that thread, but none of them worked for me
