I am having a hard time studying with ROBOTIGNITE virtual machine. Help!

Hello!
I am a student studying Ross.
I accidentally deleted some libraries from the virtual machine of ROS BASICS IN 5 DAYS.
So I am in a difficult situation to study ROS.
I searched several places, but there was no button to return my virtual machine to the first.
If possible, please tell me how to reset my virtual machine.
Is there any other way if that doesn’t work?
thank you!

Hi @this0paper,

Just close the browser tab and come back in 20 mins. You’ll get a new VM automatically.
