Installed Visual Studio Community (2015) and cannot use Database from 2013

database

Have been using Visual Studio Express 2013 and just installed Visual Studio Community (2015). When trying to open and access my Database Tables when running my old Project inside VS 2015 I received the error "The database 'D:\SSC_POS\SSC.MDF' cannot be opened because it is version 782. This server supports version 706 and earlier."

I then deleted all instances of the Database and created a new Database and tables within VS 2015 and loaded my data scripts, but I am getting the same error!

Checked my Installed Programs and I have SQL Server 2012 Express LocalDB AND SQL Server 2014 Express LocalDB (plus components for SQL Server 2008,2012 and 2014)

I Installed the VS 2015 although VS Express 2013 was already on my System.
Do I need to deinstall some of the SQL Servers? If Yes, which ones?

(I am very new to this Forum so if I knew how to paste an Image here I could show the complete list of installed SQL Server Components)

I am grateful for any help :)
