No, it is a licensed copy through the MAPS partnership. The evaluation version was 2012. I have uninstalled it, rebooted, etc. I then installed SQL Server 2014 Standard and now have the issue the database engine won't start.
I would look in the Windows event viewer in the control panel and also in the SQL Server error log. That will be in C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log or possibly C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log. There's a file called ERRORLOG which should tell you something.
