Hi Matt,
What version of TBC are you using? Be sure you are on the latest, v5.00.2, if you are working with a previous version. Beginning in what I believe was v5.00, TBC only needed the valid ReCap license for the RCP export to work. For versions prior to v5.00, there was a specific installation order needed... ReCap first, then TBC second. This could potentially be causing this error message.
If this isn't the case, message back and we'll look into it further.
Something to look forward to, the team is working on an export that stablizes the RCP exporter, does not need a copy of ReCap to work, and support ReCap 2020.
