SQLite.net out of memory error on simple insert

I'm using http://ift.tt/1MyTcyX .

Here is my table class:

class SyncTime
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    public DateTime RunTime { get; set; }
}

And my data class which is being called to insert the current datetime into the table.

 public class DataLayer
    {
       SQLiteConnection db;
       public DataLayer()
        {
            // Initialize the database if necessary
            using (db = new SQLite.SQLiteConnection(Settings.DBPath))
            {
                // Create the tables if they don't exist based on DatabaseTables' folder's classes
                db.CreateTable<SyncTime>();
            }
        }

        public int InsertSyncTime()
        {
            // Insert note into the database
            var syncTime = new SyncTime { RunTime = DateTime.Now };
            return db.Insert(syncTime);
        }
    }

And here is my call:

    private void Sync_Button_Click(object sender, RoutedEventArgs e)
    {
        renderUI(1);
        DataLayer dataLayer = new DataLayer();
        dataLayer.InsertSyncTime();
    }

And I'm getting a out of memory exception.

What am I doing wrong?
