Hi All,
I'm setting up my new cold coin wallet (awesome product) and have had no problem up to the step of syncing it with off line Electrum wallet.
1) I created on cold card an Electrum wallet on the micro sd card, following instructions I think.
2) I put the sd wallet in the pc, and can see the wallet etc.
3) I install Electrum from verified install file, and open the testnet version of Electrum.
4) I attempt to open the wallet file from cold card and get an error message
"Cannot load wallet invalid extended key format " etc.....
as shown here:

Many thanks in advance.
