I need help

As a Vietnam Vet with troubling anxiety I think that this program could be veery helpful. Unfortunately I'm 76 and I'm not a computer genius. I have spent hours trying to get this program to work. despite the many questions I sent to the Zendesk I've only got one answered. I seem to get to the session I wanted however without sound or anything happening on the total virtual reality monitor screen. Does anyone have any suggestions as to how to get the program to work or how to get ahold of someone who will answer my questions? rick7058
