Improvements

• Supports MS SQL Server 2014
• Implemented the interface on the Wizard to the store procedures "sp_delete_backuphistory" and "sp_delete_database_backuphistory"

Fixes

• If the connection authentication was configured like Windows Authentication and the backup type was Script, an error was generated and the backup was never executed
• The Waiting form now shows on the center of the screen
• When no task existed and the option "Add backup task - Add a single database backup task" was clicked, an exception was raised
