Everything has been working fine with beta5 for months. A simple upgrade to beta6 and the card has stopped working.

I did file tech support order earlier in the week, but no response yet.

Also... does anyone have an image for beta5 that they can send me
(LHG)

I did an OTA update so I never had a copy.

Do not open new tead, use Beta6 thread instead.

Thanks for the pointer. The downgrade DID get the EC-25V to function correctly again.
