Hi,
as you say you have 2 codes, one is BF3 LE and the other Premium (not premium edition)
and together those form the PE pack. Since you already activated both and appears used
things should be ok.
Origin lists BF3 standard and LE but not premium in "my games". It only shows premium in
the game details.
Right click the game and choose view game details. Scroll down to expansions. If premium
was unlocked, Origin should show premium and all DLC's in full color and not greyed out. You
should be able to download the expansions as well.
As to the disc error, I think normally the PE pack is BF3 standard + Premium (why use LE as
you would have 2 Karkand DLC's) and it could be you got a standard disc with a LE code.
But this is just guessing.
[edit] or it could be, when first activating the codes and then using the install of disc it will not work.
Once a code has been activated on Origin the disc setup will not work. You can still use the
disc for installation but you will have to leave the disc in (do not start setup) and use the
download button in Origin. Origin will detect the disc and use it for installation and download updates.
