None of my effects library is showing up

Hi, I'm new to this software so I can't figure out why this has happened. Basically, when I first used the software a couple days ago I was trying to learn how to use it so I was trying to put some Video FX into my timeline. It didn't let me do this and instead urged me to buy the full version of the software. Another possibility is that my effects library may have stopped working since I attempted to install the newest version. Every time I've been on it since, the only things it will let me add from the effects library is text. I've tried uninstalling the software and reinstalling it. I can't seem to find anything about this on the forum either. Any help on this would be much appreciated, thanks.
