Help with isolating traffic for SW578, 11 Jan 16, divert to ATL

[msp2anywhere]

Longtime listener, first time poster.  Usually have liveatc.net running in the background while i'm plugging away at the computer...

I was on SW578, 11 Jan, FLL-MDW, when we diverted to ATL due to a cardiac arrest.  I'm looking to isolate the ATC recordings.  I did give a half-hearted attempt yesterday, was unsuccessful, but I still consider myself a novice at culling the raw data to find what I'm looking for.

Any assistance is appreciated.

Safe travels.
