1) I did not know i have to be a registered user to use this module.
Not a registered user, a trial user or a paying customer.
2) I used only 1 email address to sign up with - that being my mail email address.
I see now. It was my understanding that you were either a trial user or a paying customer.
3) Can you actually tell me what is going on here ? - I got refered to this forum from joomla.org so i registered here and downloaded the module. Why is it that you will not answer my posts ? Do i have to have membership to this site or what ?

There's no membership on this site. I refrain from answering posts from users that don't have either a trial or a full licensed version of jReviews because in the past I have found out I had been helping users with old, pirated copies of jReviews. You can't use this module without the jReviews component because the advanced search capability is in jReviews, not the module.
