The dynamics of charm quarks at the RHIC can be approximated by the Langevin equation, a stochastic differential equation which evolves the distributions towards the thermal predictions. We have extended this approach to charm quark-antiquark pairs, which also experience an attractive interaction measured with lQCD. This model has some agreement with the measured anomalous suppression of J/Psi yields in Au+Au collisions at the RHIC. We now also consider the possibility of recombinant J/Psi production in heavy-ion collisions, which may increase the J/Psi yields in some collisions significantly. We find that by considering recombinant production, we may achieve agreement with even the latest analysis of R_AA/R_CNM, where the observed suppression is quite smaller than previously thought.
