Battlefield 1942 - Road to Rome & Secret Weapons of WWII on Origin

[potentialmonkey]

Right, so recently found my copy of the Battlefield 1942 WWII Anthology.  With my new PC, i don't have a CD/DVD/BR Drive, so can't install from disc.  I've managed to activate the original 1942 on Origin, but it's not accepting the codes for the Road to Rome and Secret Weapons of WWII.  

Anything i can do to get these on Origin?
