Hi Steve,
Have you tried to delete manually the PrestoPhoto cookies in your browser?
See this post where Bayla and me had problems to log in:
viewtopic.php?f=15&t=5050
As a matter of fact, I still must login every time, but at least, I can log in with my saved login and password. I had to delete the forum cookies and block the forum to write cookies for this. It seems there is a lack of sync in login for PrestoPhoto and the forum in your case.
