I am unable to record or add a new track. (WaveLab 11.2 trial version)

I downloaded the trial version of wavelab 11.2, but I am unable to record or add a new track. The tutorial doesn’t help me at all. No matter how much I follow him, I get nowhere. I cannot buy a license without knowing the basis of how this version of WaveLab works!

WaveLab Elements or Pro?

Step by step how do you setup your system PC or Mac e.t.c
