refocus plugin

I've tried all the suggestions I can find. I've loaded it, unzipped it properly to the plugin folder. I've even gone as far as restarting my computer and restarting gimp. Nothing seems to work. I've tried the one off of devart and the one off of sourceforge. I downloaded a newer version of winzip so I could unzip the sourceforge one, and it unzips it into a million files, also known as 129, and I can't figure out where to put them all.
Somebody help me please I've spent enough time on this that it would be completely wasted if I come out empty handed.
