halo 2 problem

Well I was currently using the Killtrocity v2 map-pack for halo 2, had to delete the new maps and stuff, but i made a big-mistake and forgot backup the $u folder which I think lets the game know you have those maps, any idea where I can find them?

 

the $u folder is your XBL updates.

 

so, technically you dont need them.

 

Then why can't halo 2 see the new maps anymore? I don't get it?

 

bacause when you change the .xbe's in the H2 maps folder(dont remember the name) it doesn;t read them so the killtrocity maps can be read.

 

Ok so how do I can fix this, so halo will read the new maps?

 

get the three updates replaced.

 

So would I have to get back on live, or is there ones online I can download?
