Ahhhh. I bet I know what the issue is. Someone reported something similar to me via email earlier this week.

Are extenders in use for your project? Are you using Jon Welfringer's simulator patch? Without this patch to allow sim to talk to real extender, you will likely get ActionList errors and Page Text will say "Connection Failed" when you try to execute an action intended for the extender in the Simulator.

In order to simulate without Jon's patch, you should remove the extender fro the component.

Finally, when you download this to the real remote (with the extender activated for the component), do you have the same issue?

If you want to email me to config, please do so and I'll have a look.
