there are a couple of machine keys in your web.config file that must be retained. If you did'nt back up the web.config or you lost your keys, you have to redo your membership records like Keith said. These keys are the keys used by the membership providers to provide password access.

>I've upgraded from DNN 3.00.13 to 3.03.04 and now I can't log in with the admin or the host accounts. The passwords must have been reset during the upgrade. Which of the SQL tables are these stored in so that I can overwrite them?
