Accidently delete "Authors Term List" ,any way to recover?

Hi there,

I’m a very new learner of Endnote. 

I was supposed to reformat the “Journals Term List”, and then I stupidly deleted the “Authors Term List”. I tried to reopen Endnote with an early version of Library, but seems not to work, now all authors’ names are in red. 

Does anyone know how to recover this please?
