1. Could not connect to the specified instance.
2. MySQL error number 1130.
Host ‘localhost’ or ‘127.0.0.1’ is not allowed to connect to the mySQL server.

Connection problem in mySQL sever is the problem that will encountered when mysql is not perfectly installed. Removing instances,uninstall and re-install the mysql still the problem was there. Other way to solve this issue is the System Restore.

Try it, if cannot, do research again.
