no notes only strange lines

Hi,
I have just updated to Dorico 3 . When I start new score,I only get strange stripes- no notes,
what do I do ?


It looks that you have a problem with fonts. Try to restart the computer and see if that solves the problem.

Welcome to the forum, rossis. Try following the basic procedure at the top of this page to clear your font caches, then reboot your computer.
