While trying to open Porsche Wikitude App...a window opened reading "Version no longer supported. Please update." When I press "ok" the phone's browser takes me to a non existing linked site key.
Could you please clear your browser cache and try to install the version again. If this does not solve your problem, please deinstall WikitudePD and install it freshly via the AppWorld.
Should you have further questions, please contact blackberry[at]wikitude.com
