Hey! No, you're not wrong, I had used a tool to generate the image version of the font from the actual ttf file - not sure what was specifically wrong with the config, but the output is non-standard and I had trouble using it semi-recently, and did get some better results converting again with different configurations, but I never got beyond a few test files with that, so not sure which of those are actually usable.
I'll possibly try and upload a better bitmap version at the weekend maybe if work lets up. In the meantime, you may make much smoother progress generating a png version with the exact specifications you need yourself from the .ttf file, there's a bunch of free/open source tools that can do that!
