Adding MyBB forums to my Wordpress Blog

Advert test
My site is being hosted by Blacknight at the moment and its fare to say they need to add to there web app list. They have SMF & phpbb forums but not MyBB. I was trying to upload on my Blacknight Cp and it just wouldn't allow me so I took it to my FTP (File Zilla) and started uploading till all the files were failing and stoped with 607 files left to go.
Would anyone here have a clue of whats the problem and how to fix it?
