Anyhow, to be able to have the latest updates for Vue 4 Pro (there is a very recent one), you need to be registered at e-onsoftware with your serial number. If your serial is recogniced, you will be able to update. If it is not recogniced as a valid serial, then you are lost, unfortunately. But if ever you have purchased your copy at a legal reseller with (as Dale said) (1) Have been in a rigid box that opens from the side. (2) Have a 461 page manual, with the licencing agreement on page 461 (3) Have the 3 CD's in a cardboard, triple fold protector as large as the manual that has a shortcut reference printed on it, among other things, and (4) A registration card and a rigid envelopes of Vue scene postcards. If all that was not there, then you may have a problem. then just tell me and I will get a contact for you at e-onsoftware. But I can do this ONLY if you have all these things, and an invoice of your pourchase.
