Newbie here.  Built my first photogallery and when saved it goes into a juice_box gallery folder and when I create a second gallery and save it, I get a dialogue box telling me files will be overwritten.  When I click yes, the first file is overwritten by the second. 
Second issue, when I open Juicebox Pro and go to "open gallery" nothing happens.  What happened to my saved gallery?

Please advise.  Thanks, Bob
