Click the "Log In" link at the top of the main page there's a link within called "Forgot Password" or something like that. Click that and the software will email your password to whatever email you set up your account with.

If it doesn't work let me know and I'll delete your account so you can create a new one.

And yes, for everyone else reading this, some accounts don't currently have an email address and that's a problem on my bug list.
