Sorry to hear that your first experience on this server was so disappointing. I can really not say more than don't get disencouraged, try it again and find out yourself where people stick around. Maybe you were on at an uncommon time or just had bad luck?
You can of course not expect to run into people all the time, the map is just too big for that, and one hour without interaction seems not so uncommon to me. But imo the survival aspect also makes DayZ enjoyable when you are on your own, and eventually you will also experience these days where you stumble across one group after another and have hours of great rp.
Besides, you can always join a group and stick around with them, just have a look at our forum and get to know some people. (Can't send you the link to groups section as I am on phone)
Btw, don't forget to make at least one post in the forums soon (introduction doesn't count), so that your account won't be deleted.
I wish you a lot of fun here and hope that you'll soon have memorable encounters. See you around!
