use filezilla to get it in your GAMES(Z) directory and it should come up on multiMan, not sure if blackops works yet :S but it should deffo show up in multiMan
also this should be in the question section...
For people who have downloaded BO. When you have transfered the game to internal or external hard disk then just download the latest patch and install it prior to starting the game from multiman.
I downloaded my copy of BO and can run it no problems with fifa11 in the drive, by the way im running it from an external hard disk.
