DotNetOpenId & mdash; & Ldquo; This message has already been processed & rdquo; Error


I'm starting with OpenId using the dotnetopenid library and, so far, so good, but when I try to login, it shows me the following message:

This message has already been processed. This could indicate a replay attack in progress.

The first time I used my app it failed and, after that, the above message it is always returned.

How can I "logout" the user that I'm using for testing or how can I can clear the request so I can login/logout?

Thanks in advance! =)

I found the problem, a seely problem as usual...

I was calling the GetResponse more than once, and that got me error message.

Sorry for the inconvenience and thanks for your answers =)
