Backup loaders and game updates?

Hey guys, just threw the kmeaw cfw on my ps3 tonight, and all is going well. Just a quick question tho, I'm using multiman and I threw on uncharted to the hard drive and it plays great. It does ask for an update to 1.01 and when I try to download it, it either goes into an infinite loop of trying to apply the update, or it gives an error code. How do I go about applying updates to games launched from multiman or other game launchers?

Thanks!

I had that problem for AC Brotherhood, and I fixed it by completely removing the game files and game data and ftping the game back in again. Everything was peachy after that.
