Purchased Photoshop CC on a monthly subscription and Lightroom was part of the package. Downloaded Photoshop and it works fine, but when I went back via the CC app to get Lightroom, it wasn't in my list of available or downloaded apps as it once was. In fact, it's not visibly available anywhere except to download the trial. Using Mac OS 10.9 Mavericks.
download the trial and activate with your adobe id.
