Would Not Open??

I absolutely love this application, as an Add-On for Firefox, but as a stand alone app on my iMac....well it wouldnt even open. Im not sure what Im missing here, or if it doesnt open, but it becomes a option in a right click menu? But I opened Safari and right clicked, and never saw an option for Awesome Screenshot. If you had actually provided some information on how to start and use the program, well that would have been nice. And I hate to leave a non-positive review, and I think I was generous with leaving 3 stars, because I absolutely adore this app in Firefox, but until you actually explain how to use this on my computer, and make it so it actually opens when I click it, well, I have to stand by my less than stellar review.

iMac 10,6, 3.06 GHz Intel Core 2 Duo, OS X 10.6.8
