when you create a design in ANY tangible medium, it is a "copyrighted work" owned by you - a document, a letterhead, a sign, a package, a webpage - the FONT is no longer an issue in copyright law, only the totality of the "work"
Sorry, but this is 100% wrong. I'm not saying this to start a discussion, just to make this completely clear for other readers.
Many fonts allow for personal, non-commercial use for all the purposes most people are interested in.
But as soon as you for instance design a logo, sell a PDF or use a text in a commercial video, you need expressly, written permission to do that.
Anyway, after a 4-days nightmare over this, I just found the solution -- and I'm not sure if I should post it in this forum haha, but here goes: I'm also a Windows users and I just realized that Microsoft actually has a chat service. So I chatted with a supporter and got written permission to use all the fonts I need. It took 10 minutes...
