HELP!!!!!!!!!!!!!!!!!!!!!!! tranny problem

[rcbeast]

i was driving my bl emaxx and it was kinda making a clicking sound but i didnt think anything of it (probably just gear meshing was what i was thinking)

i was driving it then i stopped to pick something up and then when i tried to go again it didnt want to move...
i took the motor and everything off and tried to free roll it across the desk and the wheels lock up after a little rotation. (this is rolling it forwards and backwards)

please help!!!!!
