you didn't get a time out message in the RX update app did you? I did a few times, but ultimately got to 100% and it finished. then I could bind, after changing to the protocol that MZ uses. (on the Evo board). In all, quite a messy process! It took me over an hour to get one TX and 3 rx's to work again. Since everything worked fine before, I'm not it was worth it.
