I had a designer design my logo. I dont know how in the world to reach them now since I told them what happened, but someone is emailing me demanding $500 since its on our website. Two questions, the extent of the license of the font that we fond that matches when we download is the following:

"Really clear,

Use for selling = License
Personal = free"

I've been searching the forum and such and I see a lot of license fees posted that are usually $50 or less. They keep harassing us on our facebook page and I'm not sure what to do. Its just used as branding, we use it kind of like a tag on clothing, but its not that the logo is used for selling tshirts. Before the designer went MIA I told him about this and he said he traced it because its not just a font, its a vector added as well. Does anyone have any experience with this. I emailed the designer from a different email and asked what is there license fee and they wont give an answer. Its coming from a foreign country and we are in the US.
