Studio theme question

I had studio them installed by a developer several months ago. I just installed the updater plugin and put my API key in, but it is not recognizing my studio theme I am running and there is an update available. I just got a 12 month membership today. can someone point me in the right direction to get the theme updated? I think there are sum bugs I am experiencing that I need to get worked out. Please don't assume too much. I know enough, but am not an expert!
