Frame numbers in EaselJS start at 0 instead of 1

I've read older threads discussing how this is just an error message and should not cause major issues so, perhaps then, I am not executing properly. Made a simple clip with boat attached to classic motion guide path. Plays fine in animate but when i test movie in browser this error message pops up:

Frame numbers in EaselJS start at 0 instead of 1. For example, this affects gotoAndStop and gotoAndPlay calls. (3)

In the browser only the waves (a static component) are shown but there is animated boat, no options for play/pause, etc.

What do i do next?
