Adobe Editions Issue with Macbook

I am having trouble getting into my account on Adobe Editions on my Macbook. I had Adobe Editions installed on my previous laptop and also have it on the app on my phone. I am able to install the program however I don't know how I'm supposed to access the book I've already bought. I can see it on my phone and the account associated correctly. There is no button or sign-in on the program on my Macbook so I don't know how I'm supposed to access anything. I was also told to authorize the download to my computer using my adobe login information, however, that does not work at all.
