mysql_connect Error

Hi,

I have recently switched to a new hosting providor and cannot access my site online - production.

I have setup the credentials correctly but keep getting this error:

Code:

Message: mysql_connect() [function.mysql-connect]: Access denied for user 'username'@'xxxx.arvixe.com' (using password: YES)

My new host is Arvixe. They have been unable to help me resolve the issue and was hoping someone might have some insight on how to resolve my connection issue.

If I need to provide more info, let me know.
