iOS OpenFeint submit highscore problem

[Bartos88]

Hi, I'm trying to include OpenFeint in my game but I'm having some trouble. I can now display the leaderboard for my game with:

[OpenFeint launchDashboardWithHighscorePage:@"123456"];

But when I try to submit a score to the leaderboard as follow, it just does nothing:

[OFHighScoreService setHighScore:score forLeaderboard:@"123456" onSuccess:OFDelegate() onFailure:OFDelegate()];

Apparently other people do have succes with that piece of code, so I don't understand why it's not working.

Is there anyone that has experience with OpenFeint and can help me out?

Thanks

ADDITION:

I also have a second question, I just checked the console and it prints this upon initializing openfeint:

2011-05-22 15:43:07.947 BalloonGameTutorial[6847:207] Using OpenFeint version 4262011 (2.10.1). https://api.openfeint.com/
wait_fences: failed to receive reply: 10004003

First of all, the readme of openfeint says "NOTE: Make sure your application is using https://api.openfeint.com/dd" , but mine is apparently not using /dd. Can I change that anywhere?
