I'm not sure I understand exactly what you problem is. Are you having a problem with apploader stopping, not loading, or what? Where in the process are you having issues?
How long are you waiting for it to finish? Sometimes it takes a while. I usually just let it load and go get a cup of coffee or do something else, and then check it in around 45 minutes.
You may need to download the OS again. It seems there are corrupted cods in the file. I would uninstall the OS from the computer, download it again, then try to load it.

Middbrew is very right. The missing or corrupt net_rim_theme_BlackBerry6_480x360_b_01.cod will give you the black and white screen. It's not loading up the default theme. Are you shrinking anything out before loading up the OS? If so, load up the full OS without shrinking anything. See if that helps.
