I'm also having this problem! I removed the app, did a hard restart of the iPad 2 (64GB 3G), and it worked again for a while. And then it crashed again.
The crashing occurs for me both at startup but also, when the app does manage to start, during use. So this seems like a general crashing problem, no matter how many crash reports Apple reports.
Thanks for working on this, RAF. I love this app...when it works!
