[URGENT] OpenFeint integration problems

Hi guys, I really need help here, so even dropping a few hints would be awesome.

Basically, I tried to integrate OpenFeint with Unity iPhone, and its been working decently well so far, except for 2 major crashes...

1) I haven't gotten this problem before, but my friends have. What happened is that during the first time they open the application, after going through the OpenFeint introduction screen, the game crashes. But only that once. After that, everything is fine and dandy.

2) When I exit the application via the home button, and return to it, the game crashes...

I commented out the audio things already, and ApplicationBecomeActive and the like (to make OpenFeint actually begin working)

Someone please help!
