If no .vbo data files are being created by VBOX Sim, there a number of steps that can be taken to try and rectify the issue.
Check that the required task to enable telemetry from the game has been carried out correctly. Click the 'Getting Started' link, located at the bottom of the 'Help' tab in the VBOX Sim software to view the requirements for each game.
If you using the version of VBOX Sim supplied with the VBOX Sim Pack, ensure that your VBOX LapTimer is plugged in and powered up. Data will only be recorded if a VBOX LapTimer is plugged in.
