There were actually 2 other things I meant to mention above.
1) After I registered, it said I would get an activation link. I never received this, but I did receive a "New User" email with my username and email (just no way to activate). This could easily be causing me my issue of logging in.. could you activate my account and I'll see if I can log in then?
2) When I try to login, I'm not seeing any system messages. This is usually something that needs to be put in your template and they show any errors or messages that components want to show. This can usually help diagnose an issue by showing "Account not activated" or "Incorrect password", etc.
To add the system messages, in your template's index.php file, somewhere you should include the following line. Then, any messages will be printed to this area of the screen, if any are created:
<jdoc:include type="message" />
Hope this helps. Somewhat of a tangent from the original issue, but possibly related.. or will help to diagnose.
