I just downloaded version 2.0 from the app store.  When I open the app, it just shows Genesis 1 (not the text, just the title) -- and I can't view anything else.

 

UPDATE

I just deleted the app and redownloaded & installed it.  It works now.

Same here, got the splash screen and then it crashed to the iPod Touch's home screen. Delete and re-install worked for me too. I am running the 2.1 iPod Touch software. Ccromp, is that what you are also running? Could be this just be an issue with the 2.1 system?
