same here, but also for the .skp files. Even with a new created 2015 pro version models i am forced to open in 2014 so i get an error. If i can not solve the issue (since i do not want to run 2015 version and then open the file via browsing or from the list below every annoying time) i guess i am going to uninstall the 2014 version.

Any help will be very appreciated.
