Musicmatch Jukebox 10 Plus

I recently had to reinstall Win XP home serv pack 2 on my XPS laptop. I forgot to write down my preinstalled musicmatch plus key. I de-partioned the hard drive, just the c: drive part not their other partions, repartioned and reinstalled the OS. When I originally purchased the system about a year ago I puchased the option of Dell Jukebox Premium - Jukebox PLUS w/lifetime upgrades to future versions. I didn't recieve a cd with music match on it nor did I get the key written down anywhere on my order info or the info that came with the computer. If it is somewhere on these forms and papers let me know. I downloaded musicmatch from the Musicmatch website and it asks me for the registration key. Problem is since I didn't write it down I don't know it. After much time spent on the phone and in "chat" with dell technical, I still don't have the key. The best they could do was have me email Muicmatch with my info and what has happened. I think this is silly I purchased the registration/upgrade key through Dell. Why do they not have it in my file? I doubt Musicmatch will be of anyhelp if they even get back to me at all. Tech support has been nice but is a joke since they obviously have no clue what I talking about when I try to walk them through my problem. I understand them through their accents and such(which is a different subject. I was told the call center for XPS was exclusively in America one of the reasons I bought a XPS) but I am tolerant and try to help them understand. Unfortuantely I am out of patience. I need to know this key that I paid for. I even had a rep try to sell me software support instead for helping me find the key I ALREADY PAID FOR. I have called the XPS hotline many times and gotten nothing they don't even know what I'm talking about. Please help me.
