if the "jpeg converter" is the djpeg application that I included and you're getting that message (probably something with wording like "16-bit MS-DOS Subsystem") when you run it, that may mean you have (or have had) spyware. I've seen some malware (although I can't remember what it was) which causes just such an error message when you try to run command-line apps.

As far as Irfanview goes:

1) Open Irfanview
2) File -> Batch Conversion/Rename
3) Navigate to C:\Program Files\Out of the Park Developments\OOTP 6\Graphics\MVP
4) Set the "Files of Type" dialog to .JPG, if it isn't already.
5) Click "Add All" on the left.
6) Click "Use this directory as output".
7) In the "Work As:" section (bottom right side of the window), make sure "Batch Conversion" is selected.
8) Under "Batch conversion settings", set to Output format to "BMP - Windows Bitmap".
9) Click "Start" at the top.

You should see a progress window that goes merrily along.

Repeat the above steps, but using the following directories in step 3:

1) C:\Program Files\Out of the Park Developments\OOTP 6\Graphics\BG
2) C:\Program Files\Out of the Park Developments\OOTP 6\MLB 2005 for OOTP 6.lg\Logos
3) C:\Program Files\Out of the Park Developments\OOTP 6\MLB 2005 for OOTP 6.lg\Photos

Once the conversions are done, you can go into those folders and delete all the .jpg files.
