I've had a little bit of BTC in a MultibitHD 0.5.1 wallet for a while now. With the latest surge in price, I tried spend it at a place that uses bitpay. My first transaction probably had too little of a fee and is unconfirmed. I attempted to redo with a larger fee but it too told me was too small a fee and my attempt to buy from the store failed.
After some searching I found that Multibit is not good to use anymore / discontinued. I also came across something telling me to repair the wallet which I did but then the remaining balance became unconfirmed and not sure what to do next.
How could I get back the unconfirmed balance or confirm it? Is there anything I can do about my two unconfirmed transactions? Would it make sense to transfer everything to a new wallet software (can't when unconfirmed balance)?
