Need Help with Customize App

I have used jailbreak (newest version.... .3 i think... which both jailbreaks and installs iphone apps) on my ipod touch (week 38). i have installed the customize application, but it does not work. it starts to launch, pauses a moment, and then drops. i have no idea what i am supposed to do to make it work. any help? i'm using a macbook.

 

Thank you Dagored for your help. Contrary to vividdemise's somewhat assumptive and rude/unhelpful comments... i had come across the prior posting, and was using the mod'd file. what i was missing, and just got from your post, was the need to go into rSBT first, and change the setting to 14 or more. once i did that, customize now works. before, as i mentioned, i could never even get the customize.app to work. I appreciate your help Dagored. perhaps someone else is having the same confusion i did.
