It looks like the original post has been deleted, meaning the password is gone :/
So, that's a big problem. The only thing I can suggest is finding and downloading from a different site, I'm sorry.
Here is one that I found, I can't download it to check if it needs a password or not, and there are over 50 parts.

Sorry that I wasn't able to help you further, but without the original password it's virtually impossible to crack a rar file.
