Click this link and download either the 32 bit or 64 bit English version.
Once downloaded, it will be set as your default program to open rar files. If you save the rar files to where you want the files inside to be placed, then all you have to do is right click the rar file (should be a file that looks like 3 books) and click extract here. It should be done quite quickly dependant on the file size
Hope this makes sense to you
EDIT: Can these promotions possibly be added into the database

Unfortunately I'm not very good at wrestler stats or anything so I can't be of too much help, but would like to see Australia represented.
