RVIZ Application Not Launching

edit

Hello Im trying to run an RVIZ application from the Udacity Robotics-Nanodegree but unfortunately when i try to run it it crashes with this message:

You can start planning now!

I can run RVIZ Perfectly without any application, but when I try to run this one it crashes. This is very weird because many other students have opened it without a problem, so its not application related.

I am Currently stuck in the program because of this problem. If anyone can help me it would be greaaatly appreciated!!!
