I am trying to load a roboat urdf.xacro.

Months ago I could dowload the robot model correctly than later I realized an upgrade in terminal and I could not launch more the robot motion planners correctly. So I uninstalled ROS and installed again. Now when I try to load the robot in Movelt setup assistant the system returns me the following information:

[ERROR] [1565264134.964861920]: Could not load resource [package://g500armdescription/meshes/robot/ECA/arm4.3ds]: Unable to open file "package://g500armdescription/meshes/robot/ECA/arm4.3ds".
