Google API Sucks...

Okay so i'm using the .NET library that google wrote for their API, and while testing login with invalid credentials i ran into an exception, something about captchas, but anyways, i extracted the URL from the exception opened it up in a new dialog, and got the answer from the user. But i can't figure out how to send the damn captcha answer to google... Maybe i just suck at googling, or i'm too tired, because the only captcha required exception handling exception uses a different version of the .net library...

Can someone help me?

EDIT: Crap this should really go in the C# section... Oops
