Hi firezombie444
What plugin did you download?
I'm using cranberrygame 's plugins and the work fine. Just download the plugin, unzip it, close C2 and create a new folder witht the plugin name at /install-path/Construct2/exporter/html/plugins/...<YOUR NEW FOLDER>
Then copy the content (..js files and so on) in this folder.
Then open C2 and it should work
