Hello Jam79,
Sorry for the problems with finding how to get to WordPress. You do not need to download WordPress. It is easily installed through the cPanel interface. You will first need to login to cPanel. You can then use Softaculous to load WordPress very quickly. Once you have it loaded, make sure to check out the WordPress education channel if you have any questions on using WordPress. If you still want to download WordPress, you simply have to go the WordPress home page in order to get the installation file.
I hope this helps to answer your question, please let us know if you require any further assistance.
Regards,
Arnel C.
