Download it from here. Drop it into your plugins subdirectory (If you’re on WPMU, have your Site Admin drop it into your mu-plugins subdirectory.) Should show up on your Dashboard -> Presentation -> Sidebar widgets page.
Update: Well I learned my lesson in releasing something to the WP community. Last time I do that. I’ve gone ahead and deleted this widget. I’ve tried to help folks who were having issues and followed up with their questions but folks wanted me to play guessing games and didn’t want to give me any information so that I could help them. They just wasted my time and theirs. I also didn’t care for those bad mouthing me elsewhere while not even asking for assistance or even reading the instructions.
