Effectively ravco and bigz89 received v104 machines without programming - this is why I stilll think that wiping the programming is the quick fix.
From posts over the last 10 days or so, Expressvu have denied this works, but the only reliable fix posted on this board seems to me the one that reciptrap and I were lucky enough to get. Whilst others have posted since then on failure to update with Expressvu input, I do not see it mentioned that this approach fails
All the other approaches seem to fail , at least in the short term - resets, reconnections, power off etc
