"Divx player has encountered a problem and needs to close."
Divx is a codec that is probably needed to play the video.
Open Add/Remove programs from the Control Panel, uninstall Divx, and it's player and then go to the website, and re-install it. You may find that'll fix the problem
Just make sure you select to not use the PRO codec when intalling, because I think that has a time limit on it.
