Just downloaded and extracted Rainbow Six Lockdown. On installation, and about 2/3 of the way through the install, the installer requested I insert Disk 4 in order to run data5.cab. Checked the unzipped setup folder and there isn't a data5.cab file there. This is the download version and I shouldn't need any disks to complete the installation. Anyone have similar experience with this game or similar problems with others?

Running Windows Vista if that helps.

Where did you download it from?

Don't know which server it was. Used the ubisoft site to purchase and download.

i bought the game at a store and it comes with five disks and every time it asks for another disk you put in the next one buy the game and put in disk 4
