Membership 2 PRO still no pro after purchase of license

Hi!
I tried the free version of Membership 2 and now purchased a pro license in order to use some pro-version-plugins. I downloaded the WPMU DEV Dashboard and as I recall downloaded the plugin and installed it via upload. But the Membership 2 pro plugin still thinks it is non pro. Also says in WPMU DEV / Support:
Installed Version: 4.0.0.5 Last Version: 1.0.2.2
Also the help-page says: "You use version 4.0.0.5 of Membership 2 This is the Free version of Membership 2 - did you check out our PRO version already?"
