from the looks of this thread you hav eonly had this since january. the trainer should not be failing that quickly. and a FW update should not be the solution unless they shipped a product with a known FW bug. but it sounds like it was all peaches and cream for you in the beginning. i doubt more rides are going to make s difference.
if you unplug and remove the bike does the trainer move smoothly? on my old kicker i could grab the flywheel and spin it easily. when doing that it should come to a stop and rotate in reverse for a degree or two. sort of like back emf in a motor dissipating.
