dark_jedi, you do use par2 files to fix corrupt rar files. If you use quickpar (available at http://www.quickpar.org.uk/Download.htm), you can see which rar files are broken. If any need to be fixed, you can download some of the par files that were posted with the original files to fix them. You need to download enough par files to fix the missing chunks, but quickpar will tell you when you have enough. You run quickpar again to check if you have enough and it will fix the files.
