Just as a side-note, there are font auto installers (they were popular in the RMXP times since XP doesn't have those Fonts folder shenanigans,
back in my days...), and there is also a script from ForeverZer0 that loads fonts to the memory, and lets you use them kind of like Ace's vanilla Font folder does. It's for XP, though most of it are Win32API calls so it COULD work in VX/Ace too. No MV though since it's in Ruby.
I leave it here just for... educational reasons? Sharing information? Something like that. And just maybe it could help you xD.

Now the important question here is, why is the font not loading properly as any other font? Have you tried other fonts? Maybe even from the same font family? (like, you're using the bold version, so try the italic one instead, some fonts come separated in files by styles). I'm intrigued because I had as a given that any font would work the same, heheh...
I can't leave any stone unmoved! I must investigate! "orz
