UPDATE: I can’t believe I didn’t try it earlier – I deleted the Pro version theme, reloaded the free one, and voila! And it still looked okay after I uploaded the Pro xml. I must’ve jacked it up without realizing.
I have to go through the setup stuff again – lost the animation for everything BELOW the top section I wrote about – but at least the original issue is fixed. If I can’t get back the lower stuff, I’ll open a new thread.
