Harry: I hate to be presumtuous, but if he is confused by \"your download may be corrupt\", then I have little hope for him understanding your solution.

Tucharam, try Harry\'s suggestion to see if any of your .part files are corrupt. If you don\'t understand what you\'re doing, I\'d suggest re-downloading all of the files and trying again. Do not use a download manager, such as GetRight or FlashGet, as these programs have been known to cause problems.
If you still receive the same error, you can download the full installation file
here. This file is all the .part files already combined, and is around 100mb to download.
Good luck, and post back if you need more help.
