Am I likely to have more success getting Scholar/Membership working for me now than I was when I gav

I spent a lot of time trying to get Scholar and Membership to work and finally gave up and signed up with another Membership software provider 14 months ago. My site might function but it doesn’t look as good as it did using WordPress. Do you think that if I try to redo it now, that the theme and plugin have evolved sufficiently that I can get it up and going relatively quickly and easily? I know I haven’t retained much of what I learned during the many months I worked on trying to get the WordPress site to function. Is there any chance I can retrieve what I had made earlier? Can I keep my site active in it’s current guise while I try setting up the WordPress site? Thanks.
