premium.wpmudev.org login problem

I clicked on a link in your newsletter today and tried to log in. It rejected my email address, saying that there was no such account.

I went to one of the websites where I have WPUDEV dashboard installed, and logged in there, then went back to the page and refreshed it, and I was logged in.

Any idea why I can log in through my dashboard but not through your website?

Thanks,
Russell
