I can't reproduce this issue with the steps you have provided. Can you clarify your method of adding new users, is this via the desktop Manage > Users window, as opposed to the web UI?
Please can you create a test user and then send me the PlayIt Live data using this tool: http://downloads.playitsoftware.com/DiagnosticsTool/PlayItDiagnosticsTool.exe
I can then take a look. Please include the password of the test user in the reference when sending the data.
All sent :)
I just tested the data you sent with the user you created and this works as expected. Please can you confirm the exact build numbers you are using for both PlayIt Live and PlayIt VoiceTrack (via Help > About)
