Gpx patch not reading a font.

Hello all,i have a new font for gpxpatch which is very similar to the font that f1 will use in 2018 on the tv overlays.
The font is working fine on my pc I installed it and it's fine but when I installed it in the gpxpatch fonts folder and after modified the .ini file in gpxpdata folder I tried it in game but it won't work,the game keeps showing the old font,anyone who can help please?I can send the font file over no problem.
Thanks
