Photos Import Error

Hey guys, I've been searching online everywhere, but I can't find the solution to the problem. Whenever I open Lightroom on my laptop, it doesn't let me add photos. Every time I click it, nothing happens. I know this isn't a problem on my laptop alone because I just built a pc and tried it on there. It also failed on there, so I was just wondering if anyone online knew the solution. I've been needing to edit a lot of pictures, and they're stacking up. I don't think it's my plan because I use a school account and I checked and all the applications were still there and under the plan. Photoshop works fine I don't know why Lightroom isn't. Please let me know if you know the answer!
