A problem with logging in to a site

[arinazin]

when I attempt to log in to buxp.org I see this

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'buxp_site'@'localhost' (using password: YES) in /home/buxp/public_html/config.php on line 32
Cannot Connect

I attempted to contact them from my invite e mail which has a link to their site for questions and got the same message as above

same message on both IE and Firefox

It was working fine yesterday and I did not violate any terms of service only thing I changed was a few updates to Windows and Yahoo messenger was updated

so I have no way to contact them to ask for help and can think of no reason I should be blocked or denied access

So what is wrong and how do I fix this? My next attempt might have to be from another location and computer to see if that's it
