Update for Oasys

[twice]

I bought a used Oasys secondhand from a seller who didn't. know the first owner I do have system recovery discs and LAC-1 unlock codes. Also, I would like to receive the latest update system 1.3.3.I think To get this, I tried to register on korguser.net, but after entering the serial number and public ID, the registration system tells me that the tool is already registered. I live in Denmark so I turned to KORG Denmark with a request to help, but I was told that they could not help because Oasys first owner is reg. on Korg .net and that owner need to transfer the reg. to me but they could not tell me his name. So can someone help me maybe send me a copy of the latest update I will be glad.
What else can do in this situation?
Help with advice, please!
