License Activation Issue

On a computer with eyeshot installed, my developer changed the "computer name" and I get the following error. How do I fix this?

devDept.Eyeshot.EyeshotException: 'Another instance of Eyeshot with the same license is running by user ParkXX_PC on machine 210.xxx.xxx.xxx. You need an additional license for yourself (KimXX-PC).'
