So I had an Electrum wallet on my Macbook that was linked to my Trezor. One day, after having opened the wallet, it urged me to update my Electrum wallet (it was a rarely used wallet so old version of Electrum). After I updated Electrum, I got the message that the new wallet doesn't support this wallet type, and that it would save it as 2 different wallets? Something like that, can't really remember.
Now the problem is that after this, I can see my balance, but the wallet can't connect to Trezor and therefore I can't move my coins. I have tried to export, and tried to connect on my PC, but I get the message "Connection failed" when trying to send, and the Trezor icon in the bottom right is red.
I'm using Win10, with the latest version of electrum. Anyone know how to get it to connect? I have tried with Trezor bridge both installed and uninstalled.
EDIT: I have the latest firmware on Trezor, and it works without problems on trezor.io
EDIT2: I tried to go File-New/Restore and chose Hardware Wallet, but Electrum can't even find my Trezor, even though it works perfectly on wallet.trezor.io. Again, Windows 10
