Select "Fonts" from the "See Also" panel at the left of this screen.

To select more than one font to add, press and hold down the CTRL key, click the fonts you want, then click on "OK"
So this is what you are doing when trying to install the font?
Try saving to your desktop and then double clicking the font file and clicking install. What OS/Version of windows are you using? (vista, 7, XP, etc.) Thay all can install fonts different ways.
Nope. Rodolphe (the webmaster) has to delete it for you.

This is not a font. It is a graphic created for the company.
What do you mean "trendy blocky ones like it"?

Your font has to be approved before it shows up on the site.
Try restarting the computer, then try installing again.
I think it is Avant Garde Bold but your image is very small.
Do you have another computer? try downloading fonts on that computer, then see if they re valid. Otherwise, your internet connection may be the issue
