Hi, I have titles that include museo 300 and 700 font. I have downloaded and intalled both and the are visible in fonts on PP. However, when I open my old project i get an error saying the fonts are not saved locally and that it will return to defualt fonts.
Generally any font issues (for me) are resolved by 'deactivating' the font(s) inside the Creative Cloud app and/or signing out of Creative Cloud and then signing back in.
Of course this is assuming you have loaded Museo via Creative Cloud?
And if you haven't - then try installing them using Creative Cloud and perhaps delete the local versions?
If the problem persists with your old project, try changing from the default font back to Museo inside Premiere Pro using the Effects Controls, Essential Graphics or Legacy Titler panels (which ever one you used to create the original text).
