Lightroom wouldn't launch so I looked on the forum and saw the suggeston of signing out and signing back in on the CC app on my desktop. When I signed back in, it won't let me open it and asks me to buy it again. When it does open, it says the catalog is already opened. I JUST got this last month so I'm extremely frustrated.
