In summary, here's what the new installer does:
1. Check if the specified instance of SQL 2005 is installed, based on the user settings on the first configuration dialog box of the BP2X installer.
2. If SQL 2005 is found, skip the rest of the actions related to installing SQL Server.
3. If SQL 2005 instance is not found (you may have more than once instance of SQL server on your machine), create one.
4. The creation script first checks if the SQL setup file is found with Broadcast Power's installer, if so, it executes it with the appropriate commands. If not, you will be propmpted whether you would like Broadcast Power's installer to download MSSQL's installer from Microsoft's website.
5. After the download is complete, the executable is run with the appropriate commands.

The first feature is the addition of a line-in funtionality.

There is a new button on the Players' tab which allows you to control audio playback from the line-in. I am planning on including the line-in as a media type where you can schedule it similar to any other audio file. Also, I will add a configuration setting for the line-in to allow you to control the audio level drop for other players when the Line-In button is pressed. Currently it will drop down the audio level for all other players by about 60%.

To start playing back audio from the line-in, simply click on the Line-In button.

In addition to simply fading, you can set effects on the line-in audio, including Echo, Chorus, Reverb, etc... 

The bug
I have fixed the formatting for the WinUI plugin which exports commercials to StationPlaylist. Again, I don't have a copy of StationPlaylist, so if you find anything unusual about the file format, please let me know.
