[YouTube-API] .NET API SDK problem with API keys

Hello,
I was integrating the .NET API SDK into our website. I had to simply
upload (from a source, not browser based upload), preview and delete
video into our channel. Everything worked very well on my machine but
when I deployed all that on our live server I've received some
disturbing exceptions. No matter on what other machine different from
my PC I deploy my code my YouTubeRequest instance throws :
Execution of request failed: http://uploads.gdata.youtube.com/feeds/api/users/default/uploads

-=Stack Trace=- :

YouTubeEntry entry)
at Google.YouTube.YouTubeRequest.Upload(String userName, Video v)
at Google.YouTube.YouTubeRequest.Upload(Video v)

The inner exception is Bad Request (400).

Here is how I'm using the API :

private YouTubeRequest GetYouTubeRequest()
{
return new YouTubeRequest(new
YouTubeRequestSettings(Config.YOUTUBE_APPLICATION_NAME,
Config.YOUTUBE_API_KEY,
Config.YOUTUBE_USERNAME,
Config.YOUTUBE_PASSWORD));
}

public bool Upload(UserDto user, string path)
{
try
{
Video newVideo = new Video();

newVideo.Title = user.FirstName + "'s
findababysitter.com profile video";
newVideo.Keywords = "findababysitter.com , childcare,
babysitter, nanny";

newVideo.Media.Categories.Add(new
MediaCategory("Autos"));

newVideo.Description = "Visit " + user.FirstName + "'s
profile at http://www.findababysitter.com/profile/" + user.Id + " !";
newVideo.YouTubeEntry.Private = true;

newVideo.YouTubeEntry.MediaSource = new
MediaFileSource(path,
MediaFileSource.GetContentTypeForFileName(path));

Video createdVideo =
GetYouTubeRequest().Upload(newVideo);

m_uvRep.Save(new tUserVideo()
{
UserID = user.Id.Value,
YouTubeID = createdVideo.VideoId
});

return true;
}
catch (Exception ex)
{
ErrorLog.WriteExceptionLogVerbose("Error while
uploading video for userId :" + user.Id, ex);
return false;
}
finally
{
FileService.DeleteFileFullPath(path);
}
}

On the line Video createdVideo = GetYouTubeRequest().Upload(newVideo);
I got this exception.
My youtube details (copy from my web.config, password hidden) :
<add key="YOUTUBE_APPLICATION_NAME" value="Findababysitter.com" />
<add key="YOUTUBE_API_KEY"
value="AI39si5DrLm2t-8FG6nvORGezDYUlB_OwRb9WKB5kA3eLBQEB0hN_qondNRiW4dlzxd3GhjiBlLxWUOQe1TNxcYki27yhcDoA" /
>
<add key="YOUTUBE_USERNAME" value="tom@findababysitter.com" />
<add key="YOUTUBE_PASSWORD" value="*******" />
<add key="YOUTUBE_CHANNEL_NAME" value="findababysitter" />

Can someone help me why I'm experiencing this issue?
Thanks,
