I don't know if this is the problem. I tried waiting for BIAB to start after showing the splash screen (i.e., BIAB banner when loading the app). This message appeared:

RealTracks not found: (Style)(Set #300) 2808 Piano, Acoustic, Rhythm SoulPop 16thsMike Ev16 065

This is one of the instruments I used in the project I'm working on. However, when I open the project using this, it's working fine.

What am I missing? I already reset to factory setting but it did not solve the problem. I will take about 5 minutes for BIAB to load.
