FlexBe App not working

Hey, I’m getting this error in the course of FlexBe with ROS, I run the command that is given and the green messages appeared, but is not appearing in the graphichal interface:

Hello Denis,

This error has been solved. Now you should be able to launch FlexBe without problems.

Hey Alberto, for this error of the FlexBe App not working I think I deserve a extend of my plan for free, because It was very important to me this course.

Thanks in advance!
