Welcome to the forum. Sorry to hear you are having this problem.

When you installed / reinstalled, did you select a Custom location for your RealTracks? This is typically a different and larger drive than the drive where you might install your main BIAB program. Related, if you are using a USB drive, the drive letter for that drive can be reassigned if you plug in other external drives. There is an easy solution if that’s what is happening.

Please tell us more. Is there anything at all unusual about how you installed BIAB? Which choice did you make in the Setup as to where the RealTracks are?
