Stupid Questions

With a little research I found one of my answers out but here is my other concern.

A deep scan found a bunch of my missing music (I was a moron and formatted an external HD with my whole collection) but the free version of the software maxed out at 499 pieces recovered even though it found thousands. Is this a free versus pro thing, or is there a limitation of how much can be recovered?

No, there's no differnce between the recovery capability of the free and pro versions. Assuming you have a valid copy.
