(i don't know how to edit comments so here's an update for my problem)
I took of Fins and now "Keepin' it simple" works (i don't know why it counted with them then .-.)
Really enjoyed this game as well as the previous ones, however i have a problem with getting "Keepin' it simple" medals .-. It counted the altitude but didn't give me the medal despite having over 300k altitude w/o launchers and boosters (but with fins if that matters)
