If the solutions given there don't help, please tell us what OS you are on and what happens after following the suggestion to start by double-clicking a score.
Okay, I was finally able to get it to open through a score after a week, but now, when I open a score it displays as a blank new page. I opened every file and they were all blank. Is my progress gone?
It's better to ask for help on the Support forum. So please do that in the future. But for now, please attach one of the scores you are having trouble with.
