Q: Can I use CMA if I have purchased a complete album and now that album is part of a multi cd compilation?  i.e. Green Day Uno/Dos/Tre?

I purchased the first 2 "cd's" of the 3 cd compilation from Green Day and now they are all available to purchase as one compilation.  For some reason though, itunes is not taking the first 2 cd's that i bought off of the Complete my Album price.  Why not?
