Can't get access token for newly added twitter accounts

[alohatest50]

I am getting exception while retrieving access token from twitter.

{“Value was either too large or too small for an Int32.”}

this may be due to

public class OAuthAccessToken
{
public OAuthAccessToken();

    public virtual string ScreenName { get; set; }
    public virtual string Token { get; set; }
    public virtual string TokenSecret { get; set; }
    public virtual int UserId { get; set; }
}

userid is int in tweetsharp.dll as also same issue is mentioned in

https://github.com/danielcrenna/tweetsharp/issues/155

but why tweeter can not lunch this officially this is big bug.

Value was either too large or too small for an Int32 by using TweetSharp to get
string authUrl = twitterService.GetAuthorizationUri(requestToken).ToString();

where is the problem? help me
