Hello.  I'm running a Mac with a macOS Sierra.  I have a KeepKey with Bootloader 1.1.0 and Firmware 6.2.2 (the latest ones as of now).  I'm also using Electrum 3.3.8.

I used to be able to use Electrum with my KeepKey with no problems.  Now when I launch Electrum and try to access the KeepKey I get a message that says "Failed to decrypt using this hardware device."  Is this a problem with Electrum or with the KeepKey's Bootloader and Firmware?

I want to keep using Electrum because they have features the ShapeShift software doesn't have, like Spend from Address and Choose Your Fee.  ShapeShift wants to charge me outrageous fees to move the Bitcoin.
