I believe there's been a misunderstanding here.
Upgrading from V-Collection (6 instruments, with ProphetV and Jupiter-8V licenses on a USB-eLicenser dongle) to the latest V2 (or V2.5) versions of the included synths is free.
However, if you own the original Vintage Pack (only containing CDs for MiniMgV, Mg Modular V, CS-80V and ARP2600V), you can only update those 4 synths to their latest version (2.5/2.6) for free, but this does not qualify for free versions of Jupiter-8V and ProphetV (since you do not own a license for these two). There was a paid upgrade offer for that!
