Commented Issue: Error provisioning the Managed Metadata Service Application [19486]

Hi,
I've come across the following error while trying to install SP2013. Can anyone suggest what the issue might be?
Thanks in advance!

Also, I'm not sure why, but the ALIAS didn't work. I had set up something like SERVER\INSTANCE, but all the databases were put into SERVER. Any ideas why this might have occurred?
Thanks!
