OK, thanks. What do I do with the md5 file that is the first file (the one that comes right before the "...part01.rar" file)?
The md5 file is a sort of tool to check the integrity of everything that's included in the RAR. You don't need to use it. (but if you're not sure that everything is hunky dory, you can run it) I usually just ignore it.
