Steam account help

Hello,
Hi, i am having a problem with my steam account, or should i say accounts... i made 1 and then forgot it and made another one a few days later and downloaded 2 games on it and that account works perfectly. but the first account had a game on it "order of war" which, after watching all the WW2 stuff on tv am really jonsen to play   i have my CD key and when i try to set it up on the newer account it said that its a duplicated cd key (which it is but by me like 2 years ago) i remember the name of the account but not the passward and the security question, i got it when i was 15 and didnt think i would ever need it cause i was soooo mature and figured i would never forget my stuff so my security question is "where did you spend your honeymoon" and knowing me i most likely answered like this "iyebflkary" so i could get right to the game. is there anything i can do to get that accound back and play my damn game? lol
