CloudPebble error - changing fonts

I am working my way through the CloudPebble tutorials and am stuck n pArt 2 Customizing Your Watchface. I have exact same code as the example on github and have downloaded the true type font from there too. When I build I get the following error … Any ideas ??

I’m not in a position to test this out right now.

It is probably a good idea to try uploading a different TTF file in case the one you downloaded really is corrupted as per the error.

My Mass Effect watchface(s) make use of a custom font, so that’s what I intend to test later.
