I'm not sure if this will help but you do have to install the Obsidian driver before you can change fonts. If you have already downloaded and installed the software (found here:
http://www.saberforum.com/index.php?topic=3693.0) Then the next thing is that the software doesn't start automatically, you have to open the program.
If you are doing all of that then I suggest uninstalling and re installing the v2.0.0 software.
Beyond all of this, send deep an email at
