:Serial already used"

hey!
I am having a problem with registering my serial number... I bought the DVS PACK MK2 about 2 weeks ago and I still can't register..
it says: "Serial already used"
the pack was brand new although, and i contacted the store which I bought it from (the guy who owns it is a friend of mine) and he told me that he simply "redirected" the package to me and i sould contact the mixvibes team.. so here I am asking for help !
I would appreciate your help,
thank you in advance
