Both parts need to be joined using HJ split. This program can be downloaded for free off the web. Below is the link once again for part two. Remember when you join them remove the avi extension from the end part one and make sure both files appear identical (with exception of the .002 extension on pt. 2) before joining. You should be good to go!

Note : part one will play independently if you leave the "avi" extension on the end of it. However , remove it to join it with part two.
