Currently with C3 beta, you can just export to HTML5 website, so you cannot export to Scirra's arcade yet.
As for your issue of a black screen on other file hosts, make sure those service do provide HTML preview/hosting, and also consider checking for errors in your browser to have clues as to what may happen.
When you do consider posting the results in that topic.
The Arcade exporter provides you with a zipped archive. HTML5 Website export provides you with a complete folder. Do not zip that folder to host it online, on the contrary upload the whole folder and this should be the way to get your game hosted and working.
