AGK V2 and AppGameKit V1 are not compatible (the Player for one does not work with the IDE for the other).
If the about box says 'build 108', then you are using the V1 IDE.
If your 'My Products' page only shows the AppGameKit Community Edition and not the 'AGK V2 - Kickstarter Pledgers', that means V2 is not available to you.
I think it is only available at the moment (since it is in Alpha stage) to Kickstarter Pledgers. Somewhere there is a link that lets you still 'pledge' money and get the Alpha version of V2. The pledge is through PayPal. (At least, this was the case last time I checked in. I've been busy and away from the forum for a few months).
