Dcc not working with EZ command pluse

[Gunny]

I need help, I'm building a layout with 3 Bachmann 64301 HO Santa Fe diesel loco W/DCC and using the Bachmann EZ Command plus. All was running well when I first got them and then put them away. Today I was testing the track I laid out and the dcc loco's just sat there and went thump thump thump, but ran fine on a regular dc controller. But I tested a Kato dcc train w/the command plus and all was fine. Any thoughts?
