Is the arcade under maintenance?

Everytime I try to access my games I get a 404 error. Should I update and upload them again?

If you haven't read it yet, take a look at this tutorial:

It states that most plugins are not supported so, if you are using any plugins, your game may not work.

Hi,

We've just updated the arcade to a new version beta:

https://www.scirra.com/arcade

You should re-upload your games there with r204.2. Old arcade games will be made available in a couple of weeks (difficult to reactivate them and am going away soon but don't worry nothing is lost).

I would think that tutorial is now out of date. Better to just follow Tom's thread here:https://www.scirra.com/forum/new-arcade-beta_t129648
