I am trying to open my VMware Fusion but I not able to I receive the following notice:

"A virtual machine is attempting to monitor all network traffic which requires administrator access."

I have been using this program for more than 8 years and have never had this problem before. It is asking for a password and I don't know how to set up a password that will allow me to open the program. 

Can you assist me?
