I resolved my issue. It now works successfully.
Everyone - be sure that you do not allow the SCCM Package Source path to go straight to lp.cab - follow the directions in this article exactly. Make a directory above the language folder and place the language folder in it. Be sure the lp.cab is in the language folder.
For example - your SCCM package source for Spanish would be \\server\source\spanish, and inside the spanish folder would be es-ES\lp.cab. When you send the package to the DP's, es-ES\lp.cab will be on your smspkgd$ shares.
This step is critical. If you dont do this step, the task will deploy, but the LP will not install without any errors on screen or in the logs. I was banging my head on the desk for some time.
