PSN game .edat files..?

I've just updated to Rogero CEX 430 2.03 from Kmeaw 3.55 & so far everything seems to be OK (fingers crossed) apart from quite a few PSN games now not working.
What I don't really understand is what to do with the .edat files that many of the newer PSN games require
I'm supposed to put them along with the .pkg on the root of the SD right, but then what..? I've seen some instructions that say copy them to dev hdd0, but how & to where exactly..?

Any help would be appreciated

Thanks.

EDIT:

Figured it out.. doh! by copy/pasting using Multiman
Problem is I have two folders in the dev hdd0/home folder 0000005 & 00000011 I've copied & pasted the .edat file to the exdata folder in both of these but the game is still showing up as a demo.. any ideas..?
It's also requesting that I update.. should I..?

game is The Pinball Arcade.

Thanks
