Clarification on upgrades

[Jurriaan Schulman]

Hi Ruslan,

I currently own SDK  Valentina for Realbasic Win + Mac. I'm planning  
to upgrade to VDN Platform. Yet I only found an upgrade called SDK v1  
to v2 VDN. So my questions are what the price would be to upgrade  
from SDK v2 for two platforms to VDN platform and what it would cost  
when I upgrade to SDK 3.0 first and to VDN platform later this year ?

Cheers,

Jurriaan
