I would re-download all the patches from a different site. And if you have an ftp site, I can upload them all to you.
Worst comes to worst.. reinstall the whole game again and download the "ultimate" patch..which is all the previous patches
put in one pretty patch package. Now, eat a peanut butter sandwich and say that 5 times real fast..
You can get the ultimate patch here...
