Trapcode just destroyed my projects and my after effects

I downloaded this plugin and my stupid ahh probably messed something up during the installation, and now all my projects involving this plugin seem corrupted. I've already uninstalled and reinstalled After Effects and they're still corrupted. I BELIEVE I've removed all traces of Trapcode, but the projects remain corrupted. Is there any way to fix this? I've been trying to solve it for 3 or 4 whole days. Am I stupid?
