Why does BFR9 now require OSX 10.7?

I use this app for business. Because we have to maintain compatibility with older software for some of , we cannot upgrade our OSX beyond 10.6.8. I bought this software last year and have used it without a problem. Its wonderful. But after another employee created issues that required us to do a clean install of OSX on this machine, when I try to reinstall Better Finder Rename, now it suddenly requires OSX 10.7. I can still use the trial that renames only 10 at a time, so why does the full version need a higher OS version? Wont let me install from the app store because of that. Why the increase in system requirements?
