2.5 Password problems

Hey all, just updated my site (http://thehoot.net) to wordpress 2.5 from wordpress 2.3. Everything seemed to be working a-ok, went to sign in, said database needed to be updated, didn’t think twice about it…went to sign in, said invalid username and password. So, I reset my password, entered the password emailed to me, worked fine. Went into users, changed it, didn’t think twice about it. Went back to edit something today, not working. I do the same procedure, change password again, log out, log back in, not working, it won’t accept any password except the password that is emailed to me. Anyone else having this issue? Any solutions?
