Hi! I was working developing a URCap that starts a daemon in the back ground, I started the daemon in the init function in the daemon Service, the daemon monitor the RT client interface, it was working well in the URSim, but I loaded to the robot teach pendant and now it freeze at booting in a random percent, I still can move the mouse, so something is wrong with my URCap obviously, but what I need help with now is with the robot controller.  
How can I erase the damaged URCap??  
Is there a way to reset the UR controller system??

Thanks a lot, I just solved by erasing the urcap by terminal and rebooting system, I figured out how to jaja, but I’ll save this for future references if I need it
