i beleve you should be able to!!
or atleest within the price you bought it for
Edit: you should be able to install every version thats within $10.99 or what ever you payed thats from that current minimum amount!
I think because I paid $10 previously, it is still locked due to it being $10.99 now, but adding $1 to it doesn't allow access... so I dunno lol
So, if the price increase each Chapter by 1Dollar, I have to buy each Chapter at full price. Or I buy it now at 50 Dollar, so I'm hopefully safe???
nice update!
