First logon problem

I have install Xibo version 1.7.7 on Ubuntu server 12.04 LTS, and i use PHP Version 5.3.10.
After the installation i can’t logged in with the user that a create at the installation.
I have reset the password with the SQL Command : UPDATE user set UserPassword = MD5(‘password’), CSPRNG = 0 WHERE UserName = ‘admin’ LIMIT 1;
But doesn’t work.
I can’t do the first log in for change any parameters

thanks in advance for someone help me.
