Problems with the CI Twitter API Library

[eluser]Xarem Nightslayer[/eluser]
Hi all

I use the library of Elliot Haughig (http://www.haughin.com/code/twitter) and now I can't update my twitter status with this class

My Code:

$this->twitter->call('statuses/update', array('status' => "test-tweet"));

reading the timeline or other requests aren't a problem but updating the status gives me back an error:

Incorrect signature

Can someone help me? I wrote an E-Mail to Elliot but he doesn't answer.

Thank you
