Error 2000 in phpmyadmin is, IIRC, is 'cannot log on to the server'.
So either the server isnt active
Or you have a permissions problem either you havent given the right userid +password combination or that user doesnt have permissions for the specified action on the specified database.
So prove the server is running, use say mysql workbench
Prove you can log on to the server through, say, workbench.
Then make certain the userid has adequate permissions on the required database (s).
I'd rather be riding on the Tiger 800 or the Norton
