i tried lots of things, but nothing is working! i have sk 15 pro, but the same thing is happening.
could you please help me?

it may be a corrupt file, have you tried others?

what extensions do you have installed?

john

yes, i tried to open others files, but it doesn’t work.
i updated the sketch pro 2016 and it’s working… but i’m not sure if it’s a coincidence or not…
