I have this problem, how i can solve?
The general workflow is to open your existing fonts, save your working files as .vfb and export new OpenType fonts. There are quite a few potential issues you need to check for before doing this though.
I would suggest you read the manual in detail.
(And to be cynical, I'm not convinced that someone who would spend US$649 on an application of this complexity wouldn't have worked through this issue).
