friendlyway composer 7

I’ve installed friendlyway composer 7, but when I launch it the application crashes with the following error message: “Font 'Verdana' does not support style 'Regular'.” How can I solve this problem?
Possibly, the Verdana font file is corrupt or damaged. To fix this problem, there are some possible solutions:
Solution 1:  Replace your Verdana font with a working one from another computer in the C:\Windows\Fonts directory.
Solution 2:  Reinstall the Verdana font from your Windows CD.
Solution 3:  If any of the standard fonts that are included with Windows are missing, you can run Windows Setup again. Setup will replace missing or changed files.
Actually, this problem can concern other fonts too, but the solution will remain the same (for the concerned font).
