I opened http://icomoon.io/app/, I selected "NEW PROJECT" and I import icon (http://templates.silversite.pl/test/Iconfont/svg/anchor.svg) and I checked it and press "FONT >" but on next view I do not see icon - only some error like on demo: http://i.stack.imgur.com/wGHYj.png
Can you help me? Do you know what I do wrong? I use Firefox 28 / Win 7
