Hi, I try to evaluate Mendix and try to develop my first app. But when I do the tutorial “Start Your First App” I get the follow error: …. FirstApp.mpr could not be opend, because it was created with a newer version of the Modeler (7.19.0.41554). I use the last Desktop Modeler from the download page (7.18.4). What can I do – is there a newer modeller? Thanks for help Oliver
