Sounds like you need to do a fresh install;

-Uninstall the game through your app manager -Restart your phone -Reinstall the game from Google Play -Wait for a long time as it downloads content -Reitre from the Porshce race at the start (or run it if you want to) -Logon to whatever profile you used before -Restore your profile from cloud -Download all content (less hickups later)

That should take care of it for you.
