City Index Demo

I registered a week or so ago with City Index - http://www.cityindex.co.uk/ - to have a go on a demo account trading CFDs.

After I registered I started the demo and waited. Then waited. The price screens constantly said "Loading..." - but I couldn't wait for ever so I bailed. My broadband was ok because I did other things while waiting for City Index to sort itself out.

A few days later I had a follow up email asking how I liked it? I don't want to come over all Seth Godin but couldn't they tell I hadn't placed a single trade?

I'm not having much luck with finding an online trading platform I like. Let me know if you have any suggestions or good or bad experiences.
