Role Center error while opening AX 2012

Hi All,

I assigned a role center for my user and when i tried to open AX it throws the error.

When i checked in event viewer, it shows like this:

An unhandled error has occurred. To view details about this error, enable debugging in the web.config file or view the Windows event logs.

Either the user, does not have access to the Dynamics AX initial database, or the database does not exist.
