SQL Express 2008 DB error

Greetings Experts!  I have a Windows 2012 R2 server that is running GFI LANguard which uses a MS SQL 2008 database to retain the search results and other information.  After a restart, I opened up LANguard and am getting these error messages which relate to the database:

[CREATE DATABASE permission denied in database 'master'.]

I select OK and then the app opens but is empty of all data (I'm assuming this is because the DB isn't loaded).  I downloaded and installed the SQL Server Management Studio but I have no idea what I'm doing with it.  At this point, I just want to get a database (it can even be a new database at this point) to be used by the app so I can deploy Windows and 3rd party updates/patches.

I took down as much info as I could when I installed LANguard when it came to the SQL install portion.  Here are the notes I have:

server01
E:\Program Files (x86)\Microsoft SQL Server\
named instance: SQLEXPRESS

instance ID: SQLEXPRESS
instance root dir: E:\Program Files (x86)\Microsoft SQL Server\

service accounts
SQL Server Database Engine: NT Authority\system
startup type: automatic

SQL Server Browser: NT Authority\local service
startup type: disabled

Account Provisioning
Authentication Mode: Windows
SQL Server admin: local\administrator


I appreciate any assistance you can provide with this!
