Greetings. Rather than perform an update of my site from 4 to 5 (in development) I removed all the files and installed version 5 afresh, then put back the connection strings in web.config to point to my database, and restored the skin. All seemed well (other than some formatting changes in the menus and a couple of graphics not showing) except that I can no longer log in as host or admin! I have been locked out off the site. I experienced this before on one occasion when I set up the site at another URL (without upgrading, just literally copying the site and db).

Trying to retrieve the paswords will not work either. I get the message "There was an error retrieving your password. No password was sent."

Any suggestions would be most welcome.
