The magnetoconductivity sxx(B) of a classical two-dimensional electron crystal on superfluid 4He is nonlinear. Experimentally, we find a contribution to sxx(B) which, at constant field B, gives sxx(B)?Jx, the current density, while at constant current, sxx(B)?1/B. For increasing Jx, the Hall velocity ?H slowly approaches the ripplon velocity ?l at the first reciprocal lattice vector, due to strong electron-ripplon interactions with the helium. The magnetoconductivity then decreases sharply for ?H>?1.
