Broken Indeed

Yes, sadly 9.29 is broken. In fact, I contacted the Developer Support line for the past week and they basically told me to "upgrade" to their non App Store version (same app as this one essentially) for another $20. It looks like 9.29 is really meant for Mountain Lion and above, but App Store did not indicate that as such. I dont know where the fault lies with this misinformation (App Store or Developer), but Developer should provide fix for those still using Snow Leopard.
