Beaver Builder does not work

Hello, I am new here and I am not very good with apps. I have recently had to get my computer replaced and that is when my Beaver Builder stopped working. I dont even thing it’s the app itself, I dont even know what it is, I had a chat with Wordpress and they could not help either. When they entered my sight from their computer it was working for them. I just need to know if anyone encountered the same issue, so I know who to turn for help. And yes, I email BB help and got no response,
Any help would be appretiated
