i have been downloading planes for a while now, but something occured, instead of opening the simpleplanes.com on the steam browser it opens it on internet explorer and downloads my planes on the computer and i couldnt find a way to put my aircraft on the simple planes App..... what do i do???
Try to open the .splane file with simpleplanes.
It seems that you are using a mac, and I don't know to do that on one.
Is there an open-with button there?
