Groove Agent 4 upgrade

I’m in possession of Cubase Artist 7.5 (that includes Groove Agent One as part of the package). Does this entitle me to the upgrade price or will I have to purchase the full version? I apologize if this is redundant but I didn’t see this exact issue explained elsewhere in the forum.

The Groove agent one in cubase is not the same as owning the Groove agent instrument/Plugin. You need to have purchased Groove agent.
