Hi,
If you have iClone3 EX then you only need to register your product with the serial number given on the page below. It is a general serial number used by all EX users. (Not EX Plus)
Just click the link below and use this serial to register on your Premium Members account. Please make sure you don't already have the product registered.

Hope this works for you.
