Infinite scroll Vantage

I know there are couple of threads exploring the same problem and I’ve read them all(at least what I found 3 or 4)

still no solution was usefull for me.

I’m using non-premium version of vantage theme, regular blog layout. suggested infinte-scroll plugin doesn’t work.

Is there a way I can enable infinite scroll feature? does it have to do with not being a premium user (I’m happy to switch, actually not being able to use infinite scroll feature, is really the only problem holding me back from switching to a premium plan)
