The 7.5 pro version came up to me with many convenient features, but also with many damn bugs. The testing feature didn’t work properly: I can only test basic latin characters (!?); and my edited and exported font was highly damaged: only basic latin characters were left (???). So I had to come back to the 5.6 version which is less convenient to use but works more properly.
Please see the FAQ — you have to register the program to get the full font to export.
I DID!! And I don’t have any idea why that was happening.
Please attach your project file *.fcp (not the *.ttf) so that we can take a look, or send it to High-Logic if you don’t want to post it in public.
