I have been playing Fallout New Vegas for a while now but only had the Tribal Pack and Mercenary Pack which I bought off Marketplace. However I installed the Fallout New Vegas Ultimate Collection disc 2 and installed all the addons and dlcs. When booting the game it says it cannot load downloadable content and says its corrupt. Iíve tried clearing system cache, uninstalling/re-installing dlcs, uninstalling/reinstalling the game however it doesnt work. Arent you supposed to see the content on the main menu of the game? I presume you donít need to burn disc 1 of the ultimate collection as its pretty much the same as the old Fallout New Vegas.
