Not able to activate trial license while using OpenNI

I am trying to use the trial license and and use a .oni file for testing ( I currently do not have access to a sensor).

I was able to change the nuitrack.config file and specify the path to the .oni file in the OpenNI.FileRecord field. I was also able to pass the compatiblity test. However, I am not able to get the trial license to activate. I’ve tried both with the way of having a license emailed to me and through generating licenses on https://cognitive.3divi.com/app/nuitrack/licenses/. Every single time, I get the error that Network Error (302): Error transferring https://cognitive.3divi.com/nuitrack/activate/ - server replied: Bad Request
Failed: License signature is incorrect. Wrong serial. Does this have anything to do with the fact that I’m not using a camera during the compatbility test, but instead a file?

To activate any type of license, you need to plug in a depth sensor. Playing the .bag and .oni files is not officially supported and used only as a debugging tool.
