log in/out

[late again]

Last Wednesday,when I accessed this site I discovered I'd been logged out-I didn't log myself out; it just happened. I can't log back in because I'm receiving the message that my password is invalid. I've emailed the webmaster and I've emailed the administrator for some help in resolving the problem. However, I haven't yet received a reply. Can someone please help me out with this. My original username is late again.
thanks
