Errors Running hover_vrpn.launch?

edit

Hello all. I am doing research for a project involving OptiTrack's Motive and getting it to work with a single Crazyflie drone. I specifically want to use the hover_vrpn.launch file as it is what I deem to work best with my situation. So, I have made a catkin workspace and the entire crazyflie_ros_cyphy folder is in there and has been built. But I found myself having to manually edit the hover_vrpn.launch file to include the full file address to launch each .launch file it references to (otherwise, it would produce "Resource not found: crazyflie_...").

Now, the issue is that the file runs, but the nodes won't launch. It produces the following message:
