Battle Net account

Ok, so I decided to combined my battlenet and wow accounts today; just to get it over with(since I know it will be required eventually). The problem is: I have forgottem my battlenet account password(I haven't used it in almost 6 mos). When I try to use the password recall, it tells me that my email address/last name combonation is not valid. I would just make a new battlenet account, but, I forsee a problem with the games I already registered not being playable due to the cd keys already in use.

I am going to assume that you already have my email account for this wow account. The battlenet account email should be the same. How can I get this fixed?
