MvvmCross - Windows Phone 8 + SQLite - Could not open database file

I am using MvvmCross to create Android, WPF and Windows Phone 8/8.1 apps. I've gotten SQLite working fine in the WPF and Android apps.

With the Windows Phone app, I am running into an issue when calling Create() on the SQLite database file.

The first time this is called, the create and open work just fine, but when the create() is called a second time it always fails.

Code:

ISQLiteConnection db = factory.Create("filename.sql");
db.Close();

Error:

"Could not open database file: filename.sql (CannotOpen)"

Stack:

at SQLite.SQLiteConnection..ctor(String databasePath, Boolean storeDateTimeAsTicks)
at Cirrious.MvvmCross.Plugins.Sqlite.WindowsPhone.MvxWindowsPhoneSQLiteConnectionFactory.Create(String address)
at MvvmCrossPOC.Core.Services.MetadataService.OpenDatabase()

I followed this article, and others with similar steps, and added the MvvmCross SQLite Plugin (v3.5 - Install-Package MvvmCross.HotTuna.Plugin.SQLite), but the error remained.

WP8 SQLite error: The specified module could not be found

Any thoughts on how to move forward?
