I haven't sent any transactions for months, but my Multibit HD wallet says my entire balance is unconfirmed. I've used Wallet > Repair Wallet several times. I've close it and opened it. There is only about 1% of the balance confirmed, and it changes each time I repair the wallet.
I see that very old transactions from 2015 are showing as unconfirmed (but they are).
I tried to install version 0.1.1 and that restored the balance, but the highest fee possible is 10,000 satoshis/KB and the current fees are 400,000 satoshis/KB so I cannot send any transactions with it.
