Well, I haven't tried to install it yet since I have the paid version of viewer and I wanted to know the upgrade cost first before messing with it.
Since all of you mention that the ovi version is the viewer and the Dataviz site is not fully updated about the premium version, I guess they made a snafu of the situation.
Someone pushed the wrong button before everything was ready.
It should all be clear tomorrow or in a couple of days tops.
