An error when i try to launch the default.launch

[Boris-Chang]

Good afternoon.

Thank you for your contribution. I am currently trying to run the roswrapper Xplane_ROS but I am facing an error when i try to launch the default.launch.

I have been trying to solve it but I have not found a way.

By any chance do you happen to have a hint on how to solve this problem?

Thanks in advance
