I have an old DNN directory and database, version 2.0.3.  I am trying to upgrade it to 4.3.7 and am of course running into issues.  First I am trying 3.2.2.  I backed up everything.  I then extracted 3.2.2 install into my directory.  I renamed release.config to web.config and added my server/database information.  I browsed to the install page and it finished without any errors.  My portal/login page opens fine.  However, when trying to login with host or admin, when you hit Enter the page just refreshes - it doesn't say invalid password even if you enter a wrong one, it doesn't log you in, it doesn't say anything at all, just reloads the page you're on, accomplishing nothing.

Of course you would ask me, did I transfer my machine keys into the new web.config file.  Well, the old web.config file from version 2.0.3 had no machine keys.  The <appSettings> section ONLY has a connectionString line in it, and that version of the site was indeed working fine for its users.  Besides, since the page just reloads without reporting any errors, I don't belive this is an authentication issue, I think it's something else.

Any help?  Thanks!
