The person who was the administrator for Creative Suite (and she didn't issue a second backup admin) abruptly left our employment. Let's just say we don't plan to hear from her again. What do we need to do at this point to change administrators for the licenses she handled?
I suppose you are talking about a teams account. The main administrator controls that, which probably was your employee leaving abruptly. So contact your vendor or Adobe. You will need to prove ownership of the teams account.
Make sure that the next main admin is someone stable. He does not necessarily be a CC user.
