Echo Valley Express 2-6-0 Not Responding

[Biggie Cheese]

I've been wanting to ask this for a long time, considering that the problem has existed for a long time. I laid my DCC & Sound 2-6-0 From the Echo Valley Express set on my table, and it sat there for a few months. I went to go run it again, and it wasn't doing the things it should. No sound and barely any movement. I think I just need to dust the engine and oil it again, but I feel like that wouldn't solve the sound problems giving that they're inside the tender. I want to run it again, and preferably really soon. What should I do to get it working again?

EDIT: I forgot to mention that it runs on the older DCC module. The new one was announced right after I got the set.

I know this doesn't help much but you said it runs on your older controller. Why not go back to that since it works? All of your other DCC locomotives should work on that one as well.

That's the thing. It's my only controller. That's my only DCC engine. I would upgrade it but... you know... It's kinda expensive. The problem is in the engine, anyway. Not the controller. The controller's fine.

Has your track been laying on a table for months and, if so, have you cleaned it?
