I have a client who we have been using the API with to create leads when someone submits a form on their website. It has been working well for many years and we have made all necessary code updates to make sure it's inline with new changes.

The client just let me know that for the past couple of months it hasn't been logging leads. When testing the code, I found that the following error is being returned:

* 4834 - Invalid Ticket Id

I logged into their account and confirmed that the auth_token is exactly the same and that it's active. I tried to generate a new authentication token using the browser method and I received the following error:

#Mon Feb 04 11:03:17 PST 2013 CAUSE=ACCOUNT_REGISTRATION_NOT_CONFIRMED RESULT=FALSE

There account is registered and has been confirmed for 3-4 years. What could cause this problem?

Thanks.
