I have a few pm's regarding the date cracker app. To me, it wasnt the best app (some people confused with date selection etc) and I myself wanted a better way to launch an application - I wanted something that i could simply launch from a shortcut and datecracker required 2 steps to launch anything (i like things simple)
So to that end I have found a better solution and thought I would post here. Its much better and more intuitive to use (and free):

Then you can simply modify the shortcut to launch your app (full instructions included with app) to something like this (your paths may differ)
C:\Data\Apps\Utils\runasdate\RunAsDate.exe /immediate /movetime 16\02\2011 00:00:00 "C:\Program Files\Caphyon\Advanced Web Ranking\AdvancedLinkManager.exe"
