"Upgrading" UTFT library

Hi guys, I am getting a compiling error for my project using using the UTFT library and was hoping for some help.

I am working on a project that uses someone else's code, I never was very good at the coding. I followed his build instructions but the person I bought by LCD from supplied me with a ILI9341 controlled screen instead of the SSD1289 that I ordered (I found this out after a couple of hours of debugging my build and re soldering the LCD shield). The version of UTFT that is included with the code supplied is not compatible with the ILI9341 controller (actually no official version is but I searched and found someone's modified library that works with this screen).

However, now when I try to compile the sketch and send it over to my MEGA I get the following errors:

Jarduino_v1_2.cpp.o: In function `TimeSaver(unsigned char)':
C:\Users\Alex\AppData\Local\Temp\build4591064788993806302.tmp/Jarduino_v1_2.cpp:1741: undefined reference to `SevenSegNumFontPlus'

It appears that I am missing a font? So perhaps the UTFT library included with the project was also modified. Can I somehow add this font back to the library, or is there another workaround?

I also can't seem to figure out how to open any of the library files, like those .h files that I read people talking about editing. If I need to edit those, how do I go about opening the file?

Thanks in advance.

Yes you can add the missing font from here.

I was able to find the SevenSegNumFontPlus font there and add it. It now compiles perfectly.
Thank you very much.
