UFC Undisputed 3 missing files

When I downloaded UFC Undisputed 3 for my ps3, it was missing some files and it wouldn't get recognized by my system. I have downloaded this in the past and it worked fine but I had to redownload. Any help would be much appreciated :)

Also shout out to Vimm. I've been using the site for a long time but just registered recently. Great stuff dude.
